Bug Description

I run RPD on Ubuntu 11.04. When I put in a camera and choose RPD, it recognizes the camera but doesn't show any photos.

$ rapid-photo-downloader -d

Thanks for your bug report. I'll need to change the code to account for cases where the program can see the camera is mounted, but is denied access to any of the files on it (which is what is happening).

Meanwhile, I am asking the Gnome developers why access to the files is denied.

If you want to use Rapid Photo Downloader, the best workaround will be to use a card reader.

summary: - RPD doesn't show photos on camera
+ crash when trying to scan inaccessible files on mounted camera
