That's odd. I've overwritten this method but it never get called.

This isn't shown at the console but in error-dialogs. The message is 
"Error while updating status of command: Publish". Beneath Publish there 
are errors for Revert, Update, Status, Commit and Log.
Starting MD with --debug didn't help to get better stack traces.
The second attempt to display the context menu works always great but 
all items in VC submenu are inactive.

Thank you for your help!

If you want to have a look on my code (and tell me everything I do wrong 
;) ) look at
