# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

pixman: pixman is a library that provides low-level pixel 
pixman: manipulation features such as image compositing and  
pixman: trapezoid rasterization. 
pixman:

This has nothing to do with pixman, it's a bug within xserver
specifically exa that was already fixed in git master,
if you are experiencing something different compile all of your code
with -g and -O0 flags and attach Xorg pid to a gdb to get a
traceback when assertion strikes. http://cgit.freedesktop.org
/xorg/xse...93b2a28f6de316, 
http://bugs.freedesktop.org/show_bug.cgi?id=22642.

Recompiling xserver shouldn't be that bad if you get all of the necessary 
prerequisites. The 35758544813f156eaac28844e693b2a28f6de316 commit 
will be making its way into 1.6 stable branch, it is on the wishlist:
http://wiki.x.org/wiki/Server16Branch, as an alternative you 
could try patching your distro's current xserver with this particular 
commit.
