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 <gphoto-de...@lists.sourceforge.net>, 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 There is no file in folder '/'.

Something uninitialised maybe? As this bug is causing problems for F-spot and gthumb, etc, can it be prioritised? ** Attachment added: "Tar file with failed log (1st time) and working log (2nd time)" http://launchpadlibrarian.net/48596075/debug-files.tgz -- libgphoto2 causes F-Spot import failure https://bugs.launchpad.net/bugs/301731 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
