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

[list at heinrich-muenz.de]

I've tried importing my f-spot database into shotwell 0.11.1 today. Raw+Jpeg works fine now, but there are still the same issues with tag imports from f-spot. Espacially the error ("L 2467 2011-08-31 13:29:24 [WRN] No namespace information for
>> XMP-Präfix `lr' available") is quite annoying, because it makes shotwell crash. 

Isn't there any workaround? I'd really like to move from f-spot to shotwell, but I don't want to tag a few thousand photos manually.
