I forgot to add that I also get these errors when I run gThumb from a terminal:
(gthumb:31542): GLib-CRITICAL **: Source ID 745 was not found when attempting to remove it (gthumb:31542): GLib-CRITICAL **: Source ID 748 was not found when attempting to remove it They however only appear when gThumb generates thumbnails. When browsing images in full screen they do not pop up, but extremely slow image rendering persists. So I do not think they are related. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307127 Title: Too slow to use, and feature missing!
