Segmenation Fault when showing Texture Actor

[Anthony Batchelor]

Simple apps that use Texture Actors cause a segfault. I've attached a simple test file, but some of the examples that come with pyclutter don't work either.

/usr/share/doc/python-clutter/examples/rects.py works
/usr/share/doc/python-clutter/examples/hello.py does not work.

I've attached a simple file to re-create the issue.
If you set FAIL to False, it will render a black rectangle. If you set FAIL to True you (or at least, I) get a segfault.

The following is the console output of the script:
==========================================================
NVIDIA: could not open the device file /dev/nvidiactl (Permission denied).

(./tmp.py:12837): Cogl-GL-WARNING **: failed to bind GLXGetProcAddress or GLXGetProcAddressARB
(0, 0) (48, 48)
Always get's here
Segmentation fault

Yep, same here.
But it also segfaults when adding a simple clutter.Label to a clutter.Stage :(

I've attached a small script, mostly based on the one Anthony posted before to recreate the issue.

I'm also using Ubuntu 9.04 with the python-clutter 0.8.0-1build1 package on a amd64 architecture with a nvidia graphic card.

Using pyclutter 0.8.0 here.

On an amd64 Ubuntu Jaunty machine, using Version 180 of the NVidia driver and an integrated GeForce 6100 graphics chip, all of the bundled examples except for "behave.py", "rects.py" and "script.py" fail with the message:
Cogl-GL-WARNING **: failed to bind GLXGetProcAddress or GLXGetProcAddressARB

Also tested on two i386 Ubuntu Jaunty machines, one with a GeForce 8800 GTS card and the other with an ATI Mobility Radeon 7500 chip. All of the examples worked on these machines (except for ending with a segfault when closed, reported in this bug: http://bugzilla.o-hand.com/show_bug.cgi?id=1590).

I can reproduce the Segmentation Fault (at start) issue on an amd64 box, and another person too.

[Siegfried Gevatter (rainct)]

Seems related to #237156.

[Jeroen Hoek (mail-jeroenhoek)]

Can reproduce on Jaunty Jackalope. A shame really, I wanted to give pyclutter a try.

People on #clutter (irc.gnome.org) suggest that the issue always occurs with the combination pyclutter, nvidia and 64bit.

[Gord Allott (gordallott)]

Also confirmed here on 9.04 - python-clutter + nvidia + 64bit.

[Matthew McGowan (mmcg069)]

I can confirm on Karmic as well. 64bit and nvidia drivers also.

[Raumkraut (raumkraut)]

FWIW, I can get the examples to work (with the exception of test-easing.py, which still segfaults) under Jaunty (9.04) by installing the "libclutter-1.0-0", "python-support" and "python-clutter" packages from the Karmic repos: http://ns2.canonical.com/karmic/python-clutter

The packages do also exist for Jaunty in one user's PPA (https://launchpad.net/~kalon33/+archive/ppa), but only as part of a larger collection of assorted packages.

[Sebastien Bacher (seb128)]

is that still an issue?

[Skyler Lehmkuhl (skykooler)]

It is still an issue for me, running Maverick I get a segfault when I try to add a text actor to a clutter.Stage.
