Description Robin Rosenberg 2008-11-15 12:19:01 UTC

Version:           1.10.3 (using 4.1.3 (KDE 4.1.3), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.27-7-generic

Kmail often krasches on startup.

running strace on kmail gives that the .mailboxname.ids is the last file opened before the crash. Removing resolves the crash issue. Both local mailboxes and IMAP can be affected.

The local mailbox displayin the troubles has ~30K mails and the IMAP (uncached) has a subfolder with >100k mail. Not subscribing to the huge IMAP folder prevents crashes there.

Hi and thanks for your bugreport. Can you perhaps attach a backtrace for the crash? (See http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports)

The backtrace is very similar.
