[gtk-osx-users] Crash in libobjc.A.dylib after processing the NSApplicationOpenFile signal

[Pete Fotheringham <pete fotheringham codethink co uk>]

Running on Snow Leopard and working with 
http://git.gnome.org/browse/gtk-osx/plain/modulesets-stable/gtk-osx.modules 
and gtk-mac-integration-1.0.1

After my code has handled the NSApplicationOpenFile signal, and 
processed the file, my application crashes.

Any ideas gratefully received
