[apport] Xorg crashed with SIGSEGV in memcpy from SavageLoadCursorImage on logout

[Tormod Volden]

It crashes after I log out. This time I had built a debug version of xserver-xorg-video-savage, so the stacktrace is more useful, I hope. (I wish there was an easy way to add the apport information to an exisisting report, other than making a new report and mark as duplicate...)

Closing as fixed, the new fixed version has been in Ubuntu for some time now.
