Segfault on basic startup about gui2py HOT 2 OPEN

I get a segfault when running sample.pyw. I hadn't noticed it in my own program 
until I tried adding a menubar. The first few frames of the backtrace are:

Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

This is with '2.9.4.0 osx-cocoa (classic)' and momerath:gui2py-0.9.3 on Mac OS 
X 10.8.5.

The problem was in component.py: it was passing None to 
self.wx_obj.SetDropTarget. Maybe a bug in wx? I'm using version 2.9.4, which 
isn't the latest. I patched component.py to check if dt was None before calling 
SetDropTarget and menus now work.
