[g-a-devel] patch for the gnome-mag bug 171465

[Carlos Eduardo Rodrigues Diogenes <cerdiogenes yahoo com br>]

Hi,

Few time ago I send a patch to the gnome-mag bug 171465 throw bugzilla, 
but I don't receive any feedback about it. Anyone test it? This is the 
right solution?

By the way, I'm sending the patch attached too.

Thanks,
Carlos.
