Upgrade to xserver-1.12.
Comment 2 eandry@free.fr 2012-03-19 03:22:29 UTC 
Hi,

same issue with xserver-1.12.
Comment 3 Chris Wilson 2012-03-19 03:25:25 UTC 
So attach gdb and lets see some symbols.
Comment 4 eandry@free.fr 2012-03-19 04:03:25 UTC 
Well, according to the wiki, I need a 2nd machine to debug (that I don't have).

But abrt caught the crash, and generated some files (maps, coredump, dso_list, core_backtrace...)
What file can I provide to help ?
Comment 5 Chris Wilson 2012-03-19 04:08:38 UTC 
Using the single machine, you need to create a coredump for X. See if you already have one, otherwise it is something like:

$ ulimit -c $((1024*1024*1024))
$ X -ac -core
# recreate bug by launching rdp
$ gdb X corefile
gdb) bt

Comment 7 Chris Wilson 2012-03-19 04:20:45 UTC 
You need to run gdb on your machine with the symbols for your libraries, otherwise it is just hex...
