Comment 11 for bug 301731

I believe this could be related to bug #74279 that I have been complaining about for some time. I tried the above commands with my Nikon D300s with just the CF card installed (causes F-spot to fail) and the first time I ran the command I got this:
=================================================================
gphoto2 --debug --debug-logfile /tmp/gphoto.debug1.txt -L

*** Error ***
PTP General Error

*** Error ***
An error occurred in the io-library ('Unspecified error'): No error description available
*** Error (-1: 'Unspecified error') ***

For debugging messages, please use the --debug option.
Debugging messages may help finding a solution to your problem.
If you intend to send any error or debug messages to the gphoto
developer mailing list <email address hidden>, please run
gphoto2 as follows:

    env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --debug --debug-logfile /tmp/gphoto.debug1.txt -L

Please make sure there is sufficient quoting around the arguments.

=================================================================
Second time I ran the command it worked as far as I could tell:
=================================================================

gphoto2 --debug --debug-logfile /tmp/gphoto.debug2.txt -L

=================================================================
My own experience is this fault manifestation comes & goes, possibly with kernel updates, but then booting older kernels often shows it returning to broken. Something uninitialised maybe?

As this bug is causing problems for F-spot and gthumb, etc, can it be prioritised?
