I've found a proper way to troubleshoot it:
1. Enable Tools repository:
http://wiki.maemo.org/Documentation/...5#Installation
2. install sp-rich-core (optional: sp-rich-core-postproc)
3. Check that you have core-dumps folder in ~/MyDocs or on SD card (the last one is preferred by dumper when it's available).

And now I have three dumps but with completely different (from my pooint of view) reasons. I'm not sure which process is the last crashed for the first dump, but second is perl and third is dbus-send.
