Reporter appears to use a glib version from a ppa and not from ubuntu stock repositories.
The result of my investigation is that it is the consequence of a new check in the glib since 2.41. It is caused by the use of the deprecated function gdk_threads_init which is only needed to workaround a bug of appindicator < 0.2.9. The root cause is probably a bug in GTK itself as psensor does not directly use any gdk_thread_enter|leave with appindicator3. Fixed by http://wpitchoune.net/gitweb/?p=psensor.git;a=commit;h=43574b89d00b319eb7d7602e92a9b482ae33d760 which removes the call of gdk_threads_init when not needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1346299 Title: psensor does not start any more : Attempt to unlock mutex that was not locked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/psensor/+bug/1346299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
