Thanks for the bug report. It seems you are using the experimental nouveau 3d driver, this driver as in name is experimental and is expected to have problems and is not supported by us, but as the crash happened I am marking this bug as confirmed but at the same time giving it "low" importance. Thanks.

[Mikkel Kamstrup Erlandsen (kamstrup)]

Marked Invalid for Unity and Nux components as this crash seems caused by a bug in the nouveau driver, in some GL functionality that we have to assume is working.

If there are indicators that we can fix or work around this in Nux or Unity please reopen.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

The top of the stacktrace shows the crash occurred in libdrm_nouveau.so.1, which is package: libdrm-nouveau1a

[Mathilda Young (gtrsdk)]

I get the same crash on Ubuntu 11.10, I booted from the release LiveCD and it booted into Ubuntu 2D, then the report a bug window appeared for reporting the crash.

[Bryce Harrington (bryce)]

Hey koumus,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

[bugbot (bugbot)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
