Version:            (using KDE 4.1.4)
Compiler:          gcc version 4.3.2 20081105 (Red Hat 4.3.2-7) (GCC) 
OS:                Linux
Installed from:    Fedora RPMs

I have several IMAP accounts --- my company's IMAP and several gmail accounts --- set up. kmail seems to crash at random ever since I upgraded to Fedora 10 and KDE 4. There don't seem to be any prerequisites; leaving kmail open for 15 minutes or so and it will eventually crash.

Application: KMail (kmail), signal SIGSEGV
