Application that crashed: kmail
Version of the application: 1.12.90
KDE Version: 4.3.61 (KDE 4.3.61 (KDE 4.4 >= 20090717))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-ARCH x86_64

What I was doing when the application crashed:
I got password prompts when KMail loaded on startup.  Note that normally KMail doesn't get loaded on startup - it either crashes on shutdown or on login (I'm not sure which).  I entered passwords for both of the accounts that I was prompted for, and it crashed.

After starting again, KMail continues to ask for passwords for those two accounts (but not a third, which is on a different server), even after I have entered the correct password.

 -- Backtrace:
