Hello Vivien,

Thank you very much for the detailed report and sorry about all those
errors :(

So this one is easy, it's yet another unsupported fs type. Maybe the fix
would be to get rid of libparted fs types -> <user-partition> fs types
conversions like discussed with Danny.

Otherwise, we'll have to maintain conversions for every kind of
partitions in user-fs-type-name, user-fs-type->mount-type and
partition-filesystem-user-type procedures.
