mythfrontend 0.21 crashes on Jaunty (ubuntu 9.04) when entering screen configure

[jyavenard@…]

Running with nvidia driver 180.44

mythfrontend crashes when you enter the Screen Configuration Wizard.

This only happens with Ubuntu 9.04 for some reasons.

In MythScreenStack::PopScreen? (*it)->aboutToShow(); will cause segfault

backtrace:

Function "qFatal" not defined.

[robert.mcnamara@…]

Work, at least in trunk. Ubuntu 9.04, nVidia 185.19, r20320.

[jyavenard@…]

Should add that mythtv package that ships with Jaunty shows the same symptoms..

I've had various crashes of mythtv with Jaunty so far, the most bizarre one being a segfault in glXWaitX lin libGL (not the nvidia one)

[elkin@…]

running Jaunty with mythbuntu weekly builds 0.22.20090312-1, no crash here. Nvidia 180.44 drivers.

[Bradley Ford <wombo1@…>]

I am also running Trunk on 9.04 with no problems.

Are you running using the SVN from the Mythtv servers or from a 3rd party?

[davejohansen@…]

Replying to Bradley Ford <wombo1@gmail.com>:

I am also running Trunk on 9.04 with no problems.

Are you running using the SVN from the Mythtv servers or from a 3rd party?

I have been able to reproduce this with a clean install of Mythbuntu 9.04.

[anonymous]

Segmentation fault here too with "out-of-the-box" installation on Ubuntu 9.04 with "mythtv" package from standard repositories. :-(

[anonymous]

Same problem for me. Mythfrontend Segfault whenever leaving watching video, live or pre-recorded. Also crashes when changing channels. I am trying 0.22 trunk again.

[Dibblah]

If you want to help with this issue, please provide a backtrace. "Me too" does not help.

[jyavenard@…]

I provided a backtrace in my first report ...

[Dibblah]

Sorry - I am aware of that - I was directing the comment to the additional reports above.

Thanks.

[laga]

jyavenard, does this still happen in trunk?

[jyavenard@…]

you can close this bug, haven't reproduced it in a while (though I didn't really try either)
