When starting an app in the debugger and then stopping it via stop-jobs, the internal state of the debugger plugin seems to break down. After the first time, it eventually still allows to start the app again, but doesn't do anything when using the action. Then stopping it again a second time, all debugger actions are disabled.
didn't saw the other report already talking about this. *** This bug has been marked as a duplicate of bug 182834 ***
