Sorry, haven't been able to reproduce (haven't really tried that hard either: I have only one device and use it day-to-day work etc so doing weird stuff to intentionally break it is not an option).

But I sent a note to a guy who might be able to help you debug this in more detail.

Edit: Figured it out, I wasn't depending on a specific version of libmidgard and you have a newer version that uses libdga4, install libgda4-sqlite

Edit2: 0.5.6 in extras-devel (I have not tested it myself yet, need to go now will test later in the evening)
