Yeah everything is now working fine for me also in Fedora 15.
The only 'issue'? is as the previous poster said in the keyboard shortcuts area once you double click on an item to apply a shortcut key if you try and scroll either with the mouse or by clicking the up and down arrows, it closes the shortcut preferences for that item. You can however resize the window so if it's not showing the whole area as with the previous poster you can just resize the window and it won't close it in the process, or resize and then open the item - either way.
This is happening on all items within the keyboard shortcut preferences so it's not an issue with your plugin, and looks like it is by design anyways
Thanks for your efforts dude
