Please describe the problem:
I have a mail folder which became bigger than 2Gb. From one day to another (probably because it got > 2Gb) Evolution kept "saving the folder" at every minimal operation such change the scope to another mail folder. "saving the folder" at a 2Gb case means several minutes, so the bug perhaps is not severe but it is very damaging to the user psychological health.

I had the file:
~/.evolution/mail/local/Inbox.sdb/noname 2100000000 bytes length (round numbers).
At every minimal operation I saw Evolution was copying that file to
~/.evolution/mail/local/Inbox.sdb/noname.tmp
and after few minutes, once noname.tmp reached the size, it moved noname.tmp to noname.

Then I moved several older emails (a bunch about 500Mb) to a newer location and expunged the folder, so I have now (exact numbers):
~/.evolution/mail/local/Inbox.sdb/noname 1747968376
(for the record, the other emails are):
~/.evolution/mail/local/Inbox.sdb/Older_than_2Years.sdb/noname 444853884

Now the folder is no longer updated (no more"storing folder"), unless I expunge it.






Steps to reproduce:
I guess that by filling enough a mail box.
I'm not going to reproduce it... please developers test by feeding a testing machine....

Actual results:
In my case: unnecessary updates which slow down enormously the use of Evolution

Expected results:
Evolution be just as smart as with lower size "folders".

Does this happen every time?
Not sure. Cannot test easily.

Other information:
I'm not sure with my diagnosis. It could for sure have other causes, but the 2Gb hint is the only thing I have...
