There is also something else:

GetFullWindowProperty sometimes returns with non-zero but the result contains nothing, this confuses the window icon resolution, i.e. the $appname.xpm code path is not used.

See http://svn.debian.org/viewsvn/pkg-icewm/icewm/branches/1.3/debian/patches/misc_fixes.dpatch?view=log
for a workaround, see http://svn.debian.org/viewsvn/pkg-icewm/icewm/branches/1.3/debian/changelog?view=log for details.

In general, please include everything from misc_fixes.dpatch and i18n_updates.dpatch , various bugs are fixed there.
