There's a related bug, though, that I reported recently:

Geotagging on the N900 implies both latitude/longitude info in the Exif and thr human readable name of the place in the IPTC tags. Flickr takes the location from these IPTC tags and displays them as regular tags, which is a reasonable thing to do.

Unfortunately, the encoding of non-ASCII characters is wrong on the N900 (or rather: the encoding is right, but the information about the character set is missing), so you'll end up with a bunch of funny characters in these tags and have to delete them manually from flickr for each and every picture.
