                    canon powershot a540
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]

Version:           1.0.0-beta2 (rev.: 985025) (using KDE 4.2.90)

I compiled digikam from source following this description:

When connecting the camera the previews show up just fine but when trying to
download the images the app freezes and doesn't respond

Please verify that you can download images from your camera with the gphoto2
command line utility (Assuming Canon does not work in USB mass storage mode).

If this is fine, run digikam under gdb, make it freeze (no or high CPU usage?),
interupt with Ctrl+C, type "bt", and give us the output.

downloading via gphoto2 works fine, here is the backtrace:

additional info:

I can open the images and save them elsewhere only downloading does not work.
And digikam uses 50% of my cpu power, ergo one core completely when freezing.

Looks like an infinite loop in slotDownloadSelected.
Gilles any idea?
