Public bug reported:

Binary package hint: xserver-xorg-video-intel

Xserver frequently crashes when I start calibre and switch between different ebooks in the ebook list.
This crash is quite reproducible, about 80% of the times I run calibre. The crash happens both in unity and in classic desktop session, but only when compiz is active. When I switch of sync to vblank in compiz, the crash does not happen.
Attached is a full stacktrace. It looks like the client does not have a reference to the X request when the X reply is processed in RecordAReply.
