Bug#241014: XKB problems after upgrade to 4.3.0

[Svante Signell <svante.signell@telia.com>]

Package: xserver-xfree86
Version: 4.3.0-7
Severity: important

I get the errors shown below when starting the X server. One result is
that the <alt gr> key does not work, making keys like |\~ not to work,
very annoying. For 4.2.x versions the same XF86config-4 file worked
fine.

Error screen in Gnome:
======================
Error activating XKB configuration.
Probably internal X server problem.
 
X server version data:

You are using XFree 4.3.0.
There are known problems with complex XKB configurations.
Try using simpler configuration or taking more fresh version of XFree
software.
If you report this situation as a bug, please include:
- The result of xprop -root | grep XKB
- The result of gconftool-2 -R /desktop/gnome/peripherals/keyboard/xkb
