RuntimeError: could not create GladeXML object

[Haris Bogdanovic]

The following line gives me trouble:

wTree = gtk.glade.XML ("rbk.glade")

I get error message (subject line).

What can be cause of this ?

Here's the rbk.glade file :

> <?xml version="1.0"?>
> <GTK-Interface>
> 
> <project>
>   <name>rbk</name>
>   <program_name>rbk</program_name>
