My feeling is that this is a false positive (which is very often the
case with "unitialized value" warnings from valgrind). If anything
inside the icon_theme structure at gtkicontheme.c:1208 would be really
uninitialized you'd get some kind of error much earlier. Btw. did you
use "--partial-loads-ok=yes"? That can avoid some of the false positives
(and in some rare cases can miss valid errors, but I doubt that would be
the case with gnome-panel).
If there were no messages relating to SIGSEGV or invalid read/write,
then I think you did not manage to trigger the bug this time.
