Description Laurence Withers 2006-05-27 13:37:37 UTC
Version:            (using KDE KDE 3.5.2)
Installed from:    Compiled From Sources
Compiler:          gcc 4.1.0 
OS:                Linux

KMail crashes a few seconds after starting up. I have one (online) IMAP account, and it seems to connect to this and check what mail is in the folder; then it seems to crash, possibly during/after retrieval of the current email.

I've attached a backtrace, hopefully this will help track the problem down.

Using host libthread_db library "/lib/libthread_db.so.1".

Compiler is gcc-4.1.0, for x86_64 architecture. Let me know if there is anything I can do to get more info.
