Thanks James for helping scar to debug this issue. In this case I think 
Tommy Trussell's reply is closer to the real cause.

I've chosen to reply still to clear up some confusion about the use of 
the file extension:
GnuCash doesn't really care about the file extension. It's there mostly 
for your OS' file manager (Windows Explorer, Dolphin, OS X Finder?, 
Gnome Nautilus, ...) to know which application to launch when a user 
double-clicks on a file. With the .gnucash extension the file manager 
knows it should launch the gnucash application. Without this extension, 
you will be asked which application you want to use to open that file.

With gnucash most people won't encounter this, because they simply open 
gnucash itself, which in turn will automatically open the most recently 
used file. For most people that's the only file.

Older versions of gnucash didn't even propose the extension when saving 
a new book. That was changed at some point to improve the integration 
with file managers.
