debian: X doesn't start anymore

[arne anka]

xserver-xorg-video-glamo: 0.0.0+20090707.git98c012f7-1+b1
everything up to date.

i installed shr-[dialer|contacts|messages] and after some trying wnet to  
restart X completely, to make sure ophonekitd is started correctly.

turns out, it was a big mistake: X doesn't start anymore.
no errors, no messages, nothing but

waiting for X server to shut down

i tried different settings in xorg.conf -- nothing.
i started w/o xorg.conf at all -- nothing, well, except the "normal" log  
below it prints at the end:

""
Backtrace:
0: /usr/bin/X11/X(xorg_backtrace+0x28) [0xec81c]

Fatal server error:
Caught signal 11.  Server aborting


Please consult the The X.Org Foundation support
          at http://wiki.x.org
  for help.
Please also check the log file at "/var/log/Xorg.0.log" for additional  
information.
""

so, can some please share his xorg.conf and/or give some clues how to make  
X more informative?
simply failing without so little as an error message is rather annoying ...




here's, what i get starting X manually as root:

debian-gta02:~# startx
