Backtrace from the crash

Hello,

I have noticed that if I change the theme of GNOME using
the lxappearance program and afterwards change the theme
again using Preferences -> Appearance, gnome-settings-daemon
crashes. Please note that I believe this is a bug in g-s-d,
and not lxappearance.

Since this crash only occurs after I have changed the theme
using lxappearance, I suspected that lxappearance does
something that confuses g-s-d.

I got a backtrace from g-s-d, which I am attaching.

I have found that the problem can be reproduced with a ~/.gtkrc-2.0
similar to the following:

=== 8< ===
# The following line by itself causes g-s-d to crash
# if no other font related lines or stanzas exist
gtk-font-name="Sans 10"
=== >8 ===

If the only font related line in gtkrc is the "gtk-font-name" line,
then changing the theme using Preferences -> Appearance causes g-s-d
to crash.

While it is true that lxappearance may not be generating optimal
gtkrc-2.0 files, this shouldn't cause g-s-d to crash.

Regards,
