Created attachment 43488 [details]
from Enrico Zini, in Debian's #613830 (http://bugs.debian.org/613830), opening a given pptx file with openoffice-impress leads to an X crash, with xorg-server/1.7 (running on 2.6.32); I reproduced it with latest server-1.9-branch, and latest xf86-video-intel's master (running on 2.6.37).
I'm attaching a backtrace, which shows priv's being NULL, and intel_pixmap_is_busy() which doesn't like that. :)
Hmm, the file is too heavy for bugzilla (2MB), so I'm linking to it:
(The link is also in the Debian bug report.)

uxa: Fallback if the temporary is too large
If the render operation requires a temporary source Picture and the
operation is large, larger than the maximum permitted bo, then we will
fail to allocate the bo. In this case, we need to fallback and perform
the operation on the CPU rather than dereference a NULL bo.
