Application: kontact (4.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-19-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
The crash occured after I restarted Kontact. Before closing, the progress bar in the lower right corner of Kontact was stuck at 80%, the detailed view of this progress bar showed that it got stuck during the check of an IMAP account. Rechecking by hitting the "fetch mail"-button had no effect.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
