OTR-Plugin does not appear in pluginlist on win32
I downloaded and installed http://gajim.org/downloads/0.15/gajim-0.15-alpha1-2.exe, Installed the OTR-Plugin via the 'Plugin Installer', Put python-otr 1.0 under ~\Application Data\Gajim\Plugins\gotr (also tried ~\Application Data\Gajim\Plugins but same effect) and then restarted gajim, but the plugin does not appear in the list.
gajim.exe.log has no relevant exceptions to the plugin or anything related.
