Affects: hal hal-device-manager (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
If python produces a string from a list it 
shows it like [u'item', u'item'] this appeas typically
in the info.capabilities entry. I patched DeviceManager.py to flatten normal lists correctly
with join()-method of strings.
result is: item, item
