Comment 1 Raphael Kubo da Costa 2010-08-18 15:08:56 UTC 
Changing component to reassign the report to arysin.

I get the same crash on FreeBSD and trunk when I run "kcmshell4 kcm_keyboard". Before crashing, I get the following message on the terminal:

  Cant' open the rules file "/usr/local/lib/X11/../xkb/rules/base.xml"

Indeed, the file does not exist on my system. Where should it come from?
Comment 2 Andriy Rysin 2010-08-18 16:51:36 UTC 
Could you please specify where is your base.xml or evdev.xml file located?
Comment 3 Alexey Chernov 2010-08-18 22:44:39 UTC 
Mine is in /usr/X11/share/X11/xkb/rules/base.xml
Comment 4 Raphael Kubo da Costa 2010-08-19 03:38:50 UTC 
Mine is under /usr/local/share/X11/xkb/rules.
Comment 5 Andriy Rysin 2010-08-19 06:12:13 UTC 
ok, I've pushed some improvement for detecting xkb directory both in 4.5 branch and trunk. It definitely should help Raphael's case, not so sure about Alexey's. If you could try it and let me know if it works that'd be great.

Alexey, could you please also tell me where your X11 lib directory is?
Comment 6 Raphael Kubo da Costa 2010-08-19 15:32:19 UTC 
Hey there, I can confirm it works for me now.
Comment 7 Alexey Chernov 2010-08-19 20:48:18 UTC 
Yes, of course. My $XORG_PREFIX is /usr/X11 so X11 lib directory is /usr/X11/lib
Comment 8 Andriy Rysin 2010-08-20 01:28:23 UTC 
Ok, I've pushed one more update so Alexey's directory should work now too.

Comment 11 Andriy Rysin 2010-08-31 04:10:53 UTC 
Just to summarize:
1) improved algorithm to find rules file was pushed before 4.5.1 (and trunk) - so most of the time rules should be there
2) in case rules file can't be found anyway we now still can start keyboard kcm module, though in this case the keyboard module combo, and layouts and advanced tabs will be disabled - this will be in 4.5.2 (keyboard daemon was able to operate without rules since 4.5.0 - no nice names for layouts - only layout and variant short labels will be shown)
Comment 12 Alexey Chernov 2010-09-01 21:38:46 UTC 
Thank you very much, Andriy, for fast response and fix. Hope to try it in 4.5.1 in a couple of days.
