compiz crashed with SIGSEGV in nux::BaseTexture::GetDeviceTexture()

Binary package hint: compiz

This happens after I log in. I see unity load for about 2 seconds, and then it crashes.

Also, this can be reproduced every time I log in, if there's anything else I can do to help track this down.

[Jay Taoko (jaytaoko)]

I cannot reproduce this on my Intel laptop with the my intel core i3. This could be a missing texture. Is this bug still hapening? A fix for missing application icon was submitted 2 weeks ago in unity.

[David Barth (dbarth)]

This looks like a classic case of objects not being created properly and then using a broken reference throughout the rest of the code. If icon files are not installed properly or something goes wrong while loading icons at starteup. then the launcher will crash.

Look into Launcher.cpp in the constructor when you do a bunch of nux::CreateTextureFromFile: where are you making sure all of them are created properly?

The fix should be quite obvious after that...

[David Barth (dbarth)]

To reproduce the crash, and confirm the fix, just move an icon file and see how Unity starts

[Jay Taoko (jaytaoko)]

So far, I cannot reproduce this bug. Please, provide more info about how to reproduce if this issue is still happening.

[Jay Taoko (jaytaoko)]

Cannot reproduce. Provide more info if this is still happening.

[Alex Launi (alexlauni)]

David, can you give a very specific set of steps to reproduce this?

[David Barth (dbarth)]

I provided guildeines on how to potentially reproduce the issue: did anyone tried my instructions?

[Martin Pitt (pitti)]

This is a bug fix, can happen after FF, and isn't a release blocker.

[Jay Taoko (jaytaoko)]

Caused by missing application icon texture.
