problem generating sales orders in 1.1.12

[Marshal Newrock <..hidden..>]

We're having a problem with generating sales orders from time cards
(projects -> generate -> sales orders) in 1.1.12.  If time cards for
more than one customer are selected, it gives the error "Error! Can't
call method "prepare" on an undefined value at LedgerSMB/PE.pm line
371."  Multiple customers seems to be the only factor.

If this can't be easily fixed, is it possible to change it so the sales
order generation form comes up with everything unchecked by default?
