Ok I've investigated further and had a pointer from Andrew Clayton who fixes
this problem with a gphoto2 upgrade. The issue is a libgphoto2 one and
kernels 2.6.13+ will require libgphoto2 2.1.6 or later to work properly.

To sort this out before 2.6.13 comes out and it bites a lot of people - as
most distros will have this problem - I suggest pointing them to the bugzilla
entry as a FAQ:

http://bugzilla.kernel.org/show_bug.cgi?id=5063
