Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-020632rc8-generic x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
KMail embedded into within Kontact crashes while deleting an email in an IMAP folder from Puretec (www.1und1.de). It occurs sometimes and not reproducibly. I installed the kdepim-dbg and kdepim-runtime-dbg packages including their dependencies from debian/testing but the crash reporting assistant told me the report might not be useful. Please tell me if i need to install other dbg packages to report useful bug reports for KMail and the other KDEPim components.
