This might be completely wrong, but I seem to remember a similar issue, which I then traced down to having a masked array with a mask that was set to True or False, instead of being a full fledged bool mask array. I was in a hurry then and completely forgot about it later, so filed no bug report whatsoever, for which I apologize.
