I am running Ubuntu Studio 14.04 and I have installed OpenLP 2.0.4 from the Software Centre.<br><br>However, OpenLP does not start.<br><br>It started the first time and took me through the First Time Wizard, but once it had done that, it did not start, but just hung with the start-up logo.<br><br>It does not start properly if I restart, log out, or even kill and run it from a command line. It just shows the start-up screen and then does nothing.<br><br>Does anyone perhaps have a suggestion? Thanks!<br><br>Here is the output if I run OpenLP from the command line:<br><br><font face="Courier New">~$ openlp<br><br>(python:3240): GLib-GObject-WARNING **: cannot register existing type 'GstObject'<br><br>(python:3240): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed<br><br>(python:3240): GLib-GObject-CRITICAL **: g_type_register_static: assertion 'parent_type > 0' failed<br><br>(python:3240): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed<br><br>(python:3240): GLib-GObject-CRITICAL **: g_type_register_static: assertion 'parent_type > 0' failed<br><br>(python:3240): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed<br><br>(python:3240): GLib-GObject-CRITICAL **: g_object_new: assertion 'G_TYPE_IS_OBJECT (object_type)' failed<br><br>(python:3240): GStreamer-CRITICAL **: gst_object_ref: assertion 'object != NULL' failed<br><br>(python:3240): GStreamer-CRITICAL **: gst_allocator_register: assertion 'allocator != NULL' failed<br><br>(python:3240): GStreamer-CRITICAL **: gst_object_ref: assertion 'object != NULL' failed<br><br>(python:3240): GLib-GObject-WARNING **: cannot register existing type 'GstFormat'<br><br>(python:3240): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed<br><br>(python:3240): GLib-GObject-WARNING **: cannot retrieve class for invalid (unclassed) type '<invalid>'<br><br>(python:3240): GLib-GObject-CRITICAL **: g_boxed_type_register_static: assertion 'g_type_from_name (name) == 0' failed<br><br>(python:3240): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed<br><br>(python:3240): GLib-GObject-CRITICAL **: g_boxed_type_register_static: assertion 'g_type_from_name (name) == 0' failed<br><br>(python:3240): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed<br><br>(python:3240): GLib-GObject-CRITICAL **: g_boxed_type_register_static: assertion 'g_type_from_name (name) == 0' failed<br><br>(python:3240): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed<br></font><br>
