GNOME Bugzilla – Bug 631833
GtkToolButton incorrectly assumes that "label-widget" is a GtkLabel
Last modified: 2010-10-11 03:21:42 UTC
The following commit: http://git.gnome.org/browse/gtk+/commit/?id=dad6e7343c1fbdbbe2a6ca765aabcf8b887933c9 changes gtk_tool_button_construct_contents to assume that the "label-widget" of a GtkToolButton is actually a GtkLabel. This isn't necessarily true, and causes several warnings from assertions in gtk_label_set_ellipsize, gtk_label_set_angle and gtk_misc_set_alignment (at least in my case, where label-widget is an hbox).
This was already fixed. See bug #623603 *** This bug has been marked as a duplicate of bug 623603 ***
