Starting Drivewire with:
./DW4UI.sh


Produces the following notice I don't know how many uncountable times:

(DriveWire:2406): GLib-GObject-CRITICAL **:
g_closure_add_invalidate_notifier: assertion 'closure->n_inotifiers <
CLOSURE_MAX_N_INOTIFIERS' failed

And in between those lines lies the exception error:
