On going through the ChangeLog, I see this was in fact specifically 
fixed for version 1.9.8

Have a look at the code of your XRCPanel. It takes a single-argument, 
parent, but it calls Wx::Panel.new() with no arguments, which is the way 
it's done for loading from XRC. So you need to call new in XRCPanel with 
a correct parent argument; it will deal with the rest.

Here you're telling the Panel it should be attached to +nil+ so it won't 
display properly, or might even crash.

This is deprecated and will be dropped from future versions of XRCise - 
its use is discouraged.
