OK. Well that is three distros now that have reported the problem, Mageia 6, PCLOS, and now Debian.

It looks like the Sigil code sets up the QTreeView and then Qt takes over for the drag and drop. I put some printf's in the code in OPFModel::RowsRemovedHandler() to see how far it got. After I drop the file in its new location, I see a bunch of the errors:

Code:

Trying to construct an instance of an invalid type, type id : xxxxxxx

and then the GUI is locked up.

If I recall correctly, the execution never got to the OPFModel::RowsRemovedHandler() method, where the Spine Order is updated. So it is locking up before Sigil gets it back. I would have to double check that to confirm; my memory is vague on that.

Anyway, it looks like Sigil sets up the QTreeView and then Qt handles it.... incorrectly.. and after that the interface is partially locked up.
