[Kde-pim] KMail crash when checking for new mail

Sat May 17 19:25:25 BST 2008

Hi,

as reported on #kontact, my kmail crashes often when clicking the 'Check Mail' 
button.
I'm running latest trunk (currently rev. 808865).
The backtrace of the crash looks like this:

Application: KMail (kmail), signal SIGSEGV
Using host libthread_db library "/lib/libthread_db.so.1".
[Thread debugging using libthread_db enabled]

I hope this helps fixing the issue and KMail gets more stable.
Anyways, great work so far, I really love KMail.
