Do you know which process I should try to attach to?  This is at the
point where enlightenment is displaying a dialog saying that it has
SEGV'd.

debian-gta02:~# ps waux | grep enlight

So far I tried 1308 and 1310, unfortunately both without much useful
information:

debian-gta02:~# gdb `which enlightenment`
...
(gdb) attach 1308

(gdb) quit
The program is running.  Quit anyway (and detach it)? (y or n) n
Not confirmed.
(gdb) detach
Detaching from program: /opt/e/bin/enlightenment_fm, process 1310
(gdb) quit

I'm afraid that's probably not much help.  Is there something
straightforward I can do to find out more?

Regards,
       Neil
