Please ignore, except if you are aklapper and you are seeing this task via email notification. :)
Tasks created in a space other than the default Public have this line in the log:
Qgil shifted this object from the S1 Public space to the S2 Community-Liaison space.
I wonder whether someone could get an email notification or something because of the fact that the task seems to be created "in" S1 Public, then moved to S2.
