pyrenamer gives 'Attempt to unlock mutex that was not locked'

[sp113438 <sp113438@telfort.nl>]

hello,

Pyrenamer fails to run on my Sid uo-to-date system:

# pyrenamer 

(pyrenamer:6163): Gtk-WARNING **: GtkSpinButton: setting an adjustment
with non-zero page size is deprecated

(pyrenamer:6163): Gtk-WARNING **: GtkSpinButton: setting an adjustment

(pyrenamer:6163): Gtk-WARNING **: GtkSpinButton: setting an adjustment
with non-zero page size is deprecated 

Attempt to unlock mutex that was not locked 
Aborted


Any idea why?

reportbug gives also "Attempt to unlock mutex that was not locked 
Aborted"


Thanks!
