Re: Example programs

[Stephen Nestinger <ssn17 yahoo com>]

After looking at the latest release of Gtk+, I still
find the same code in the new version as in the old
version which caused a problem with the example
menu/itemfactory.c. This problem is internal to the
Gtk+ library in file gtkmenu.c at line 1588 of
gtk+-2.4.10 and in file gtkmenu.c at line 1632 of
gtk+-2.5.5. I believe that the line
  g_return_if_fail (accel_path[0] == '<' && strchr 
    (accel_path, '/'));
should be
  g_return_if_fail (accel_path[0] == '<' || strchr 
    (accel_path, '/'));
instead. After making this modification, the example
program works. Without it, I get
    (itemfactory.c:780): Gtk-CRITICAL **: file
    gtkmenu.c: line 1588: assertion 
    `accel_path[0] == '<' && strchr accel_path, '/')'
    failed
