Comment 2 for bug 113431

One more observation, probably linked:
if the disc drive name contains national characters, the mounted filesystem may contain invalid entries.

obexftp -l returns wise XML (C: and E: entries for my nokia E50), while after mounting this over obexfs
i get two "E:" subdirs. The C: drive's name (which is "Pamięć telefonu" in polish) is probably causing problems.
After switching the phone to english (C: becames "Phone memory") everything starts working.
