Evolution crashes when the Inbox size exceeds 2GB. As a result, when you open Evolution the Inbox will be empty, and an Error message will be at the bottom that says
Error while opening folder mbox:/home/myname/.evolution/mail/local #inbox

The solution is to archive your mails frequently. Clear your trash frequently.

 And in this particualr occasion, when your Evolution is crashing use the help of archivemail

In Fedora, perform the following.

 As root

yum install archivemail

Since I came across this issue several times I thought of blogging about it to save my time and to help any one who might need this advice.

MySQL by default has a row size limit of 64K as at MySQL 5.0. Therefore if you save a file larger than that anything after the max size will not be saved. So do not be surprised if you find the data that is saved to be corrupted.

Obvious solution to this would be to increase the MySQL max_allowed_packet variable to a very high size.

But a more elegant solution would be to break up the large file in to separate rows.Another advantage of this approach is you can read one chunk at a time and stream vs reading the
entire file in to memory.

A question that any new immigrant would ask sooner or later is, "Is Canada still under United Kingdom Rule?, or is Canada controlled by any other country?". The answer is NO.

Up to 1931, UK had significant political control over Canada. Full legislative autonomy was granted to Canada by the Statute of Westminster, 1931, passed by the United Kingdom and ratified by the Canadian parliament. In 1982, the Canada Act terminated the power of the British parliament's ability to legislate for Canada, and the authority to amend the constitution was transferred to Canadian legislative authorities.  Therefore, Canada does not pay taxes to UK, and neither does UK has any legislative power over Canada.

So that being cleared, lets find out why people even ask the question  "Is Canada still under United Kingdom Rule?". It is because of the Monarchy of Canada. Canada has a head of state not elected through a voting system. Since Canada is a Commonwealth realm, Elizabeth II is the monarch. since  Elizabeth II is the queen of UK, this gives the impression that Canada is controlled by UK. There is no provision in Canadian law requiring that the king or queen of Canada must be the same person as the king or queen of the United Kingdom; Canada has complete sovereignty as an independent country and the Queen's role as monarch of Canada is separate from her role as the British monarch or the monarch of any of the other Commonwealth realms. So the conclusion? Canada does have a monarchy, which has zero influence from UK or any other country.

Lets touch on the powers of the monarchy a little bit. First of all, Canadians do not pay any money to the Queen or any other member of the Royal Family, either towards personal income or to support royal residences outside of Canada.Normally, tax dollars pay only for the costs associated with the governor general and ten lieutenant governors as instruments of the Queen's authority, including travel, security, residences, offices, ceremonies, and the like.

The monarch is, in theory, the supreme governor of each of the Commonwealth realms, charged with issuing executive orders, commanding the military forces, and creating and administering laws. However, each country now operates under the Westminster system of parliamentary democracy and the concept of responsible government, meaning that the monarch only exercises her powers on the advice of her Crown ministers, who are usually drawn from, and thus responsible to, the elected lower house of the relevant parliament.

Neither she nor her viceroy, however, participates in the legislative process, save for signifying the Queen's approval to a bill passed by both houses of parliament, known as the granting of Royal Assent, and which is necessary for a bill to be enacted as law.

In my opinion, monarchy has played a very minor role in Canada, Australia, New Zealand, ect who share the same monarchy. But in the age of democracy, do we really need a single person to have any form of reserve powers? I guess no one bothers about this question, because practically the monarchy would not be able to influence Canada politically. Say for example, if the monarchy tries to exercise a decision against Canadians, how can she enforce it? She cannot send UK army against Canada, as UK has no involvement with the Canadian monarchy. Even if she wants to, there are other organizations much more powerful like the UN. In these modern times, it is economical ties that let one country have control over another. In a way, US president has more control over Canada than the monarchy.
