<pre>Not sure what the following means but after applying the patch from <a href="show_bug.cgi?id=44099#c11">comment #11</a>
I still get a crash when opening the image from <a href="show_bug.cgi?id=44099#c1">comment #1</a>. This is on FreeBSD
(with Radeon KMS) though.
X server stack trace:
Core was generated by `Xorg'.

Unfortunately, radeon_drv.so was compiled without debug symbols.
There are also the following messages in the system log right from the crash
time:
kernel: [TTM] Unable to allocate page
kernel: error: [drm:pid42432:radeon_gem_object_create] *ERROR* Failed to
allocate GEM object (254115840, 2, 4096, -12)
