I'm not sure, but it might be. Have you tried removing or moving aside all of
the plugins-- e.g. mv /usr/lib/mozilla/plugins{,-hold} -- and seeing if Moz
still crashes? If it doesn't, then you can restore the plugins one by one
and see which one causes the crashes.

A good suggestion. It crashes with an empty plugin directory; it also
crashes with just libnullplugin.so in the directory.

I've looked in logs, and don't see anything associated with the
crash. My .xsession-errors gets quite a lot of chatter from Mozilla
starting up:

Invalid entry (missing '=') at /usr/bin/mozilla:38
Invalid entry (missing '=') at /usr/bin/mozilla:43
.....
Invalid entry (missing ']') at /usr/bin/mozilla:65
....
Invalid entry (second locale!?) at /usr/bin/mozilla:194
....
kio (KService*): WARNING: The desktop entry file /usr/bin/mozilla has no Name

but nothing when it crashes. The system logs show

Aug 3 21:47:30 wheat gconfd (ross-30737): starting (version 2.2.1), pid 30737 user 'ross'
Aug 3 21:47:30 wheat gconfd (ross-30737): Resolved address "xml:readonly:/etc/gconf/gconf.xml.mandatory" to a read-only config source at position 0
Aug 3 21:47:30 wheat gconfd (ross-30737): Resolved address "xml:readwrite:/home/ross/.gconf" to a writable config source at position 1
Aug 3 21:47:30 wheat gconfd (ross-30737): Resolved address "xml:readonly:/etc/gconf/gconf.xml.defaults" to a read-only config source at position 2
Aug 3 21:49:30 wheat gconfd (ross-30737): GConf server is not in use, shutting down.

The final message indicates awareness of the crash, but not much more.

What a mess. The errors in /usr/bin/mozilla (a shell script-- you can crack
it open and see what's going on if you want to) suggest a bad installation.
Those look like syntax errors-- not good in the startup script.

If I were you I would uninstall, delete /usr/lib/mozilla, and reinstall (maybe
a more recent version-- 1.4 is stable now).

You may also want to try using the Debian unstable packages, instead of
building from source. apt-get -t unstable install mozilla will give you
version 1.4. Then, add

deb [url]http://marillat.free.fr/[/url] stable main

to your /etc/apt/sources.list, apt-get update, and apt-cache search mozilla
and you'll see the following packages: flashplayer-mozilla, acroread-plugin,
and mplayer-mozilla. Install these and you'll probably be most of the way to
solving your plugin problem.

Good luck,
Andrew.
