My commercial ships have no sensor at all, so its definitaly a bug.
It is a bug (known issue), but not because of the lack of a sensor....
There is a piece of mis-information upthread. When the diplomacy rules were introduced, there was a confusingly-worded statement that says that aliens get annoyed if they detect you with active sensors in their system. This statement can commonly be misinterpreted to imply that they get peeved if you're using active sensors - that is not the problem. As of a recent release (I don't remember which one), Steve changed passive sensors so that they can get a class ID; I don't remember (but think he did) if he changed the rule so that they're pissed if they detect you with any sensor (not just active).
The bug is that aliens don't realize that they've granted you trade rights anymore - they view your commercial ships as intruders, even though the ships have been invited in. IIRC, the workaround from Hawkeye is the way to fix the issue - I don't think you have to change to the other race (but I could be wrong).
