Oh, I'm missing a commit, never mind not relevant.

Yeah, that looks ok, your file is UTF-8 which is fine, the difference
in Glib shouldn't affect it, all I can think of is that its Ubuntu
specific, they are known to add patches to GTK, so maybe its one of
those?

Can you run Geany under gdb and get a backtrace?
