Hi Thomas, I tried to merge latest qt-4.8 with android-qt and I have a very strange crash at exit. It seems the same QGLContext object is deleted twice, once by its widget (check QWidgetPrivate::deleteTLSysExtra ), and once by QGLGlobalShareWidget object, but it seems I'm too idiot to fix it, so, I need your help on this one. Cheers, BogDan.
