My reproduction procedure involves more superstition than science, so it's
probably less than helpful. I can't get it to work myself when I move to a
different computer, and can't find any identifiable settings that should have
an impact:
set LC_CTYPE,
start the gimp,
open a .jpg file,
use "save as" to save to a new filename,
accept the compression settings,
select file-> close,
then file->quit.
If that doesn't work the first time... save yourself some time and don't try
again. If it does work, it seems to repeat almost every time.
I haven't figured out what's going on yet, but here are my observations so far:
(1) The LC_CTYPE environment variable is causing gimp/firefox/whatever to use
names that are localized, which creates a name_list in Flocale.c. This means
that the LC_CTYPE variable does NOT need to be set when launching FVWM.
(2) Just before the crash, I see two completely different functions causing the
same name_list to be freed.
a) The first to free is within EWMH_WMName(), when it calls
free_window_names(fw, True, False). This ultimately frees fw->name.name_list.
b) The second free is within destroy_icon(), when it calls
free_window_names(fw, False, True). This ultimately frees
fw->icon_name.name_list.
3) For reasons I do not yet understand, in the crash situation fw->icon_name
and fw->name of a different window have an identical name_list. When the
second free of the list happens, fvwm crashes.
I'll keep tinkering with this in my spare time, and I'll see what I can figure
out.
