The problem is that the old way that Qt had to tell Gtk not to use the overlay scrollbars (ubuntu_gtk_set_use_overlay_scrollbar) is now basically a noop since the new overlay-scrollbar hijacks the scrollbars at a different level (does not use os_scrollbar_new as it used to use).
It works for most Qt based programs because the new overlay-scrollbar code includes a check to not load itself if the qt_startup_hook symbol is present in the main binary of the problem, thus the issue only happens in programs like "vlc" or "bzr qlog" where Qt is loaded in a plugin of the main binary. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to qt4-x11 in Ubuntu. https://bugs.launchpad.net/bugs/1005677 Title: Re-emergence of "Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)'" Makes vlc and other Qt apps crashing crashing To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-scrollbar/+bug/1005677/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
