> Gtk-CRITICAL **: gtk_widget_ensure_style: assertion > `GTK_IS_WIDGET (widget)' failed > gtk_widget_ensure_style(tooltips->tip_window); > GdkColor c = tooltips->tip_window->style->bg[GTK_STATE_NORMAL]; This is since gtk2 2.11.6 where the GtkToolTips API is deprecated. Also see: wxGtk uses private API, breaks with gtk 2.11.6 http://sourceforge.net/tracker/index.php?func=detail&aid=1767485&group_id=9863&atid=109863
wxGTK 2.8.x is affected, too.
compat-wxGTK26-2.6.3-5 will work around this (hopefully only temporarily). The new GtkTooltip API hides internal structures, so porting the old code that accessed private members might not be possible.
