Yeah, reception via BT seems to be implemented in a strange way. Sending picture files works fine, but sending contacts files (.vcf) fails with an 'out of space' error. All of this should be handled the same way (reception of file), but it doesn't. There is an option to 'open' the file after reception, and _that_ is where any filetype-dependent handling should be implemented - not in the actual file reception. It looks like it's done in the latter, unfortunately.
