as above

I vote for this.  The q2r code does not check if you provided
the right values for nr1, nr2, nr3 (there is no simple way 
to implement this) and it does not even check if you provided
any value at all. In the latter case, unpredictable behaviour 
may follow. From the error message, it looks like 
nr1=nr2=nr3=0 .

exactly: I guess 4, 4, 4, in this case
