[Lucid] F-Spot NullReference Error while transferring photos from Kodak camera

[Jeff Lane ]

Binary package hint: f-spot

F-Spot testing found an unhandled exception while copying images from my digital camera...

The camera is a Kodak EasyShare 875. On connecting the camera to my netbook, fspot opened the dialog for importing photos. I added a tag "Kodak Pix" and started the import.

After a short while (shortly into copying the 35 pictures over,) I got an error popup that says:

Unspecified Error
Error GeneralError: LibGPhoto2.GPhotoException: Unspecified error
  at LibGPhoto2.Error.CheckError (ErrorCode error) [0x00000]

Repeated attempts at clicking Retry or Skip did nothing. Cancel canceled the operation and opened a new error box that said the following:

F-Spot Encountered a Fatal Error

The import failed and NONE of my images were copied over from my Kodak EasyShare 875

This is with the Lucid updated as of 29 March 2010.

Addendum:

After those errors were encountered, I was unable to re-connect the camera. Every time I tried, I got an error about not being able to lock the camera, THEN the Option Window would open (the one that asks what action to perform when the device is plugged in) and FSpot would launch.

However, after that, even though FSpot showed the camera when I clicked Import, I got the same object error as noted earlier as soon as I tried importing images.

F-Spot was able, though, to at least generate thumbnail previews of the images that were on the camera

Im having the same problem with my Nikon camera after i've just upgraded to 10.04. Any fix?

[James Cain (ronnoc)]

I don't think this is a FSpot problem, because I am having the same issue (or similar) in Kibuntu 10.04: When I tried copying files from a Kodak Easyshare CD14 camera, plasma crashed and now the camera shuts off whenever it's plugged in via USB.

I think there are two bugs here:

One in FSpot as it doesn't check a value for a NullReference before using it and one outside of FSpot in a library used by FSpot which leads to the delivery of a NullReference.

To fix the first bug, FSpot should be enhanced to check values returned by external libraries before actually using them.

The second bug which causes a NullReference might be this: https://bugs.launchpad.net/ubuntu/+source/hal/+bug/975588

No one seemed to take this up, so closing it, it's old.
