Unable to generate preview from existing .wxg with menu

Dear Wxglade list,

I am getting an error when attmpting to generate menu items, which 
prompts me to warn on the error (bottom of email). Im using 0.7.1~rc1-3 
from the debian testing repositories. Has anyone reported this?

The error is below (I've redacted a couple of the user-strings). This 
worked previously in debian's wxglade 0.6.8-2.2. I generated the .wxg 
file using 0.6.8 originally, and am re-opening it. I can't seem to 
repeat the bug if I simply make a new menu from scratch.

I can provide the .wxg file privately if this helps.

Thanks!
