I'm using the openSUSE package. Could have some error, but...
And then you have http://trac.wxwidgets.org/ticket/10005 saying you can't use _() there.
Perhaps you were using an ANSI build of wx instead of an Unicode one?

That makes sense, I did not realize this _() call was in a structure initialization context. The issue you're linking to makes it very clear that you're right.

The patch does not seem to break Windows build or Linux build with Externals wxWidgets, so go ahead and commit it (you seem to already have commit access to the project).
