Package: xbase-clients
Version: 3.3.5-1
Severity: normal

I was playing with xkbsel...  It compiled the system keymaps fine, but when I
tried to throw one in my user directory into the mix, xkbcomp (as run from
xkbsel) would segfault.  Turns out that the difference is that xkbsel adds an
-I option to xkbcomp sometimes...  Removing the -I option makes for no segfault.

I compiled xkbcomp with debugging symbols and ran again from GDB:

(gdb) run -synch -xkm -R'/home/kevint/.xkbsel' -I'/usr/share/xkbsel' -o '/home/k
evint/.xkbsel/compiled/kmt/kmtfoo.xkm' '/home/kevint/.xkbsel/keymap/kmt(kmtfoo)'
