Please describe the problem:
Trying to export pictures to picasaweb displays an error message, even though the upload succeeds: it says "Error uploading to gallery: the specified name does not exist: :image" and I can Retry, Skip or Cancel. At this point the picture is actually uploaded on picasa. If I choose to retry the picture will be uploaded twice, and if I skip it will upload the next picture; in both cases the error message is displayed again.

This is annoying because you have to keep clicking "Next" to upload several pictures, but apart from that it doesn't compromise any functionality.

Steps to reproduce:
1. Select one or more pictures
2. File > Export > Export to PicasaWeb...
3. Fill in the details, click OK



Actual results:
It will upload the first picture, then the error message comes up.

Fix: just click "Skip", and the next picture will be uploaded

Expected results:
Obviously, I'd expect it to start uploading the next picture automatically, without any errors.

Does this happen every time?
Yes

Other information:
Here's the output I get in the terminal:

Starting Upload to Picasa

If I skip, I get the same output for the other pictures (with different URI and index, of course)
