Bug#462942: gdm: restarts the first time username and password is entered

[Andreas Weber]

I can confirm this bug on 3 systems (2 i386 PCs and 1 notebook) with 
fresh lenny installation.

The following infos are from one PC with nvidia GPU an the GNU "nv" driver.

"Composite" is not enabled in xorg.conf

/var/log# gdm --version
GDM 2.20.3

gdm log:

The XKEYBOARD keymap compiler (xkbcomp) reports:
 > Warning:          Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
 >                   Ignoring extra symbols
Errors from xkbcomp are not fatal to the X server

syslog:

2891 crashed of signal 6
Mar 16 11:11:00 AsusBabe gdm[2884]: WARNING: gdm_cleanup_children: Slave 
crashed, killing its children

I'll try now if installing x11-xkb-utils solves the problem as described 
above.
