[maemo-developers] [maemo-developers] Debugging maemo_af_desktop crashes

I believe I've mentioned before that my 770 likes to reboot spontaneously.
/proc/bootreason is sw_rst, /var/lib/dsme/stats/lifeguard_resets usually
indicates /usr/bin/maemo_af_desktop (46 times already, out of 54
resets).  I mkdir'ed /media/mmc1/core-dumps and now have a core file
from the last crash.  Question: what can I do with it?

gdb on the 770 doesn't appear to be very useful:

/media/mmc1/core-dumps $ gdb maemo_af_desktop core.959
warning: core file may not match specified executable file.
Core was generated by `/usr/bin/maemo_af_desktop'.
Program terminated with signal 6, Aborted.

I'm still running mistral.  I've two status bar applets installed
(panelclock 0.5 and load-applet-run 0.4.3-2), but previously I've seen
these spontaneous reboots with only osso-statusbar-cpu installed instead
of these two.

(I also happen to have four other core files from previous crashes:
browser, maemo-launcher, dsme, osso_hss.)
