Created attachment 6378 Patch to fix the mismatch Due to a mismatch between gsettings schema and UI glade. (mousepad:27389): GLib-GIO-CRITICAL **: GObject property 'value' on a 'GtkSpinButton' object is out of schema-specified range for key 'tab-width' of 'org.xfce.mousepad.preferences.view': 33 ** GLib-GIO:ERROR:/build/buildd/glib2.0-2.40.2/./gio/gsettings.c:2389:g_settings_binding_free: assertion failed: (!binding->running) Downstream bug https://bugs.launchpad.net/ubuntu/+source/mousepad/+bug/1472690 Patch attached. Should mousepad really crash on errors like this? Shouldn't it be a warning, rather than an assert/exit?
Thanks for reporting and fixing. See: http://git.xfce.org/apps/mousepad/commit/?id=15f4e5a47bd85d2cd831f65d6a66e548ad4d5708
