Application: konqueror (4.4.5 (KDE 4.4.5))
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux 6.0.5 (squeeze)

-- Information about the crash:
Three times now, on logging in a new KDE session (Debian Squeeze) at the start of the day, I have found Konqueror crashing when it resumes (having been running when I logged out the previous evening).  Since I don't know what order it does things in this situation I cannot say which site it may have been reconnecting to, but there will have been several open tabs to restore.

 -- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
The current source language is "auto; currently asm".
