[SL] Strange behaviour

[JmcSoft (IRL) <in...@jm...>]

Hi

Suddenly sql-ledger will not print pdf postscript or html sales orders
or invoices, when I press print it gives a blank screen.

While trying to solve this issue if I reduce the number of products to 4
or less on the invoice it prints fine.

My httpd error logs show the following
