When I move files files into the trash or empty the trash bin nautilus crashes
and restarts.

I installed the nautilus-debuginfo, killed the running instance with "nautilus
-q" and then restartet it gdb with the --sync option to get the following backtrace:

That 0xaaaaaaaa pointer looks pretty bogus to me.
