This should be fixed.  Now, putmask accepts anything as the second 
argument and converts it to a BOOL array.  Previously it was only 
converting if it could do so "safely".   This was an unneccessary 

Scipy Core in SVN has the fix and I'll be making a new release of scipy 
core in a few days.

The problem is that it wasn't taking anything but a BOOL array.  It 
should work better now.
