Hi, I'm using KDE from sid/experimental/experimental-snapshots and since some time Kontact crashes every time I close it. What seems to be relevant here is that I have the KMail and Akregator icon in the system tray. When I start Kontact and it only shows the KMail icon, the crash doesn't seem to happen (at least not so often).
When a crash occurs, you'll get a crash dialog and on the developer tab you'll get a stacktrace and an indication (in the form of stars) how good the stacktrace likely is. I only got 1 star with those crashes, so I installed the following dbg packages: kdepim-dbg, kdepim-runtime-dbg and kdepimlibs-dbg from experimental-snapshots Reloading the crash info and/or starting Kontact again and then closing it, produced 3 stars, so it should be sufficient. Crash report attached. If the crash report doesn't contain enough info, let me know which dbg pkgs I need to install in addition to the ones I have installed. Regards, Diederik
