[Evolution] Bug#531838: Bug#531838: unusably slow since upgrading to 2.26

Yes, you are correct.  My problem is with 2.30.  The reason the subject
says 2.26 is that it sounded like the same problem that the other person
had with 2.26, so I just added more information to the existing bug
report instead of creating a new one.  (no need to inflate the number of
bugs, right? :) )

I will upgrade evolution when it migrates and let you know if it makes a
big difference, although it may be harder to determine now.  I finally
got so disgusted with the slowness that I purged about half the e-mails
from that big folder.  It was tough on the system, but I finally got it
where the folder is half the size it was before and now I'm not having
nearly the problems I was before.   I DO have a copy of the folder from
before the migration, though, so I can probably use that for testing
purposes.   

For what it's worth, this folder was my "admin" folder, so it was mostly
full of things like alerts from nagios or e-mails from cron jobs or
e-mails from fail2ban or, more substantially, e-mails from the program
logcheck.  So, e-mails could be anywhere from something really tiny to
something bordering on a meg or so in size.  As I said, the folder
itself had grown to almost 2GB.  Before purging, I think there were
approximately 38,000 e-mails in the mailbox - I now have it down to
about 18,000 and like I said, doing a lot better now.

If it still has the problem after 2.30.3 comes out, I'll let you know
and you can let me know what you need for debugging.  It just seems to
me that the program somehow needs to know it's limits and not gobble up
resources until there's nothing left.  (or would this be a malloc
issue???)  This same folder worked fine in whatever version I was
running in lenny - didn't see the problem until I upgraded to squeeze
this week.  Anyway, I'll let you know what I see. 

Thanks for your help!
