What user would be interested in such a detail if the app already run or not. In all cases a normal user inter act with thunderbird I personally know no situation where this error shows a good information.

Firefox has the same dialog, but normally only when its not responding. Thunderbird is the only app that has this dialog and I agree its totally useless as its not meant to be ran with multiple windows (even though possible, for example "thunderbird -p")
