[Kde-pim] KMail from trunk hangs on mail check (backtraces attached)

Fri Apr 4 15:59:46 BST 2008

Hi!

I just updated to trunk (including updating qt-copy to rc1).
Now Kmail starts ok, but hangs after a second on a mail check.
I have 3 accounts - two gmail-ones and one IMAP account.

Not sure which of them might trigger this behaviour - i check all at once.

This endless-looping of kmail is perfectly reproducable for me, so i
attached gdb to it.
Seems like the problem is inside KMime::unfoldHeader as i see this
function in all backtraces.

Here are random three backtraces as a result of me doing
# continue
# <Ctrl-C>
# bt

sequences in gdb :)
