Title:
With Trash bookmarked, gedit deadlocks on opening Open or Save As
dialog
Status in Ubuntu GNOME:
New
Status in tracker package in Ubuntu:
Incomplete
Bug description:
On Ubuntu 15.10, gedit randomly (about half the time) hangs when
either the Open or the Save As dialog is opened.
The cause appears to be a deadlock:
Thread 1 is in a GCancellable::cancelled signal handler, and indirectly calls
g_dbus_connection_signal_subscribe which tries to acquire a GDBusConnection's
mutex
Thread 3 is in on_worker_message_received, which holds the GDBusConnection's
mutex and indirectly calls g_cancellable_disconnect which waits for the
GCancellable's signal handler to complete.
