digikam hangs on "add collection" in preferences

[Gaël Roualland]

When going under Settings/Configure/Collections then "Add collection" in "local collections", digikam hangs. No window appear to select the collection.

Looking in debug output there is the following:

(digikam:11047): GLib-GObject-WARNING **: cannot register existing type 'GdkWindow'

(digikam:11047): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed

(digikam:11047): Gdk-CRITICAL **: gdk_window_ensure_native: assertion 'GDK_IS_WINDOW (window)' failed

Thanks,

digikam was freezing on me, I had my db and collection on a share on the local machine.
So I am trying to put them in my local home folder.
Ubuntu 17.04 and digiKam 5.4
I uninstalled DigiKam and reinstalled
When I start digikam, the configure window comes up, I click "add collection" and it freezes.
Here is the terminal output.
