Log file containing backtrace

Hi, 

On a fresh install of Ubuntu 12.10, using the (default) nouveau graphics
driver, I am able to crash the display manager by moving any window outside the
screen area.

Using other graphics-drivers (nvidia proprietary), there are no problems with
having windows outside the screen area. 


I've attached a the Xorg.0.log logfile which contains a backtrace. 

My graphics card is an NVidia GeForce GTX 660 Ti Amp Edition. 


Please let me know if you need any other log-files from the system. 


Thanks

There is no backtrace in this file.

If it crashes in NVRefreshArea, then this is already fixed in
xf86-video-nouveau 1.0.3 (you are using 1.0.2)

you're right, I must have chosen the wrong file. Sorry about that.

[Bug 59597] Segmentation fault when moving (part of) window outside screen area

--- Comment #4 from bugs.freedesktop-AKmYONJMgVsEZ6m2XrtfIFpr/1R2p/CL@public.gmane.org ---
Adding to the information originally posted.

The crash only occurs when moving a window down below the bottom of the screen
area, not right or left. 

My graphics card is produced by Zotac.
I intended to write: Zotac GeForce GTX 660 Ti Amp Edition, as the graphics
card.

I've been trying to install a version 1.0.3 driver to see if that fixes the
issue, but so far I can't find it (nouveau.freedesktop.org responds with a HTTP
503 Service Unavailable).


Let me know if I can do anything to give a better backtrace. I've tried to
install the xserver-xorg-video-nouveau-dbg package, but that didn't seem to
give any better backtrace. 


Thanks

I should note that the problem is with the 64-bit version only. 

I've installed a second test-system using a 32-bit system, and I cannot
reproduce the crash there. 

If you wish, you can close this. I no longer have a problem. 

Thank you for your time

Ok, let's assume it's fixed. Please reopen if you can reproduce it on
xf86-video-nouveau >= 1.0.3.
