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

Comment 3 Michael Schwendt 2007-08-05 20:03:37 UTC
wxGTK 2.8.x is affected, too.


Comment 4 Michael Schwendt 2007-08-06 08:38:03 UTC
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.
