[Shotwell] Two issues while trying to import from f-spot

[list at heinrich-muenz.de]

Hi,

since shotwell 0.11.0 finally supports nested tags and hiding raw files, I'd like to give it a try. So I tried to import my f-spot database into shotwell. But somehow this doesn't work. After importing a few images, an error message comes up and says:

----------------------------------------------------------------------------------------------------------------------------------------------------------
Shotwell
Ein schwerwiegender Fehler ist beim Zugriff auf Shotwells Bibliothek aufgetreten. Shotwell kann nicht fortgesetzt werden.

(TagTable.add) [19] - constraint failed

----------------------------------------------------------------------------------------------------------------------------------------------------------

(That's Ubuntu 11.04 in German; in English it's something like: "A serious error occured while accessing Shotwell's library. Shotwell cannot be continued.")

Additionally, the tags from f-spot's tag tree show up twice in Shotwell's sidebar: Once on the root level of the tag tree and once on the respective lower level. If - for example - I have a tag structure like this in f-spot:

friends
 /Peter
 /Paul
 /Mary
flowers
 /roses
 /tulips

It will look like this in Shotwell:

Peter
Paul
Mary
friends
 /Peter
 /Paul
 /Mary
roses
tulips
flowers
 /roses
 /tulips

Any suggestions?

Thanks in advance
Heinrich
