Steps to reproduce:
1. Choose export --> to web gallery from the "file" menu of F-Spot.
2. At this stage F-Spot should download the titles of the albums in Gallery2 but it doesn't, I get an empty combo-box instead with the string "No Albums" in it.
3. Choose to create a new album ("add" button).
4. Fill in the boxes, then press "Add".
