Blank brush strokes never have an oppurtunity to initialize a sculpt undo step, which results in blank global undo steps. These confuse DynTopo's internal BMLog undo stack. Note: I tried having the stroke operator return OPERATOR_CANCELLED, but this didn't prevent the undo push (which is done automatically due to the presence of OPTYPE_UNDO in the operator flags). I might investigate removing the flag, but that might cause other problems.
