can not launch any window manager after system crash

[B Thomas]

Hi,

As suggested by Bob I saved the strace output (listed below).
All I can tell is xinit segfaults immediately after accessing
.Xauthority. But am not sure why there are so many failed
library access . I did run ldconfig on seeing this but
it made no difference.

~/.Xauthority exists. It is an empty file, that is owned by me
(bt) and its permissions are 
-rw------- 1 bt bt 0 2007-08-14 03:13 .Xauthority

Any suggestions on how I can go about identifying which is
the file that got corrupted by the hard boot ? What does
one do in case of a complete Xserver/system freeze/lockup ? 

regards
thomas
