Using current Mageia Cauldron (oxygen-gtk3-1.3.3, firefox-beta-28) I experience segfaults with firefox-beta & oxygen. I usually run ff from a terminal in my wife session but this time, I opened my own session in order to investigate a gnome issue. In that session, ff always segfaulted in oxygen-gtk3. See attached trace. Oxygen::render_frame() called Oxygen::MenuBarStateEngine::animatedRectangleIsValid() with a NULL pointer... Reproducible: Always Steps to Reproduce: 1. run firefox-beta 2. 3. Actual Results: segfaults Expected Results: happy session

yes ... oxygen-gtk3 probably lacks many checks on the actual widget's validity (not null) since it was assumed to always be the case for "native" gtk applications. Now that non native apps are being ported, we'll probably end up with either - many more checks (good) - many hacks similar to what we have in the gtk2 case. I'll try firefox-gtk3 to fix this one (should be easy) and the likely many other similar crashes that will happen (less easy). Thanks for reporting, will keep you posted.

Patch fixes it. Now firefox, once started looks ugly with oxygen-gtk. Pretty much because it gets ported as poorly as it was with gtk2, and this will require as many hacks and fixes as there was in gtk2 ... I'm depressed.

This is fixed in latest version of oxygen-gtk3 (from git). Also fixed are several (though not all) rendering issues. So closing. I'll fix the remaining rendering issue once firefox-beta 'stabilizes'
