I recently notices that, although gedit-plugins 3.6.1-0ubuntu1 is installed on my system (raring i386), the SyncTex plugin is missing from the plugins list in Preferences->Plugins (gedit 3.6.2-0ubuntu1).
Could you guys be kind enough to check that you have the same problem on your system, and maybe confirm the bug I opened in Launchpad https://bugs.launchpad.net/ubuntu/+s...s/+bug/1165742
