Follow-up Comment #2:

Confirmed, retagging appropriately. The bug is not with ishandle, because
ishandle (0) is always true, 0 is the "root figure". The imcrop function
should probably not allow the handle to be zero, and it should probably
require a scalar handle rather than allow an array of handles, so that should
work to differentiate a handle from an image.
