Comment 11 for bug 1074028

Not having to also move to python 3 does make it easier. I understand that
I would need to completely redo the glade files to move to GTK3 - is that
correct? Based on other projects, the time the transition would take in
hours would be how much? Am I looking at one week of full time work, or
more like 2 weeks, or 4 weeks or more?

I've checked the gphoto2 page, and as yet there are no introspection
bindings for it. The gvfs/libgphoto2 code has been broken since it was
first developed - it works with some cameras, and not at all with others.
It seems the Gnome developers simply do not have access to a sufficient
range of cameras, so any bugs reported are apparently not fixed. Users of
Rapid Photo Downloader blame my program, of course! There is no python
binding to libgphoto2. I guess the Shotwell developers wrote their own
wrapper code for vala.
