This bug is probably easy to fix. The error message comes form
the fuction shiftQuoHypCheckAux in the file
zeilberger/shiftQuotient.mac. This checks for
all possible operators in a certain expression and does something. It
checks for "+"
but forgets to check for "-". Somebody who is slightly familiar with the
Gosper algorithm can
probably figure out how to correct this.
