[SL] ERROR - SL 2.6.27 - Not a HASH reference at SL/IS.pm

[William H. <wil...@gm...>]

Hi I have a client who has been running SL for a few years at with the end
of year etc happening now he is printing invoices and the like.

Error is as follows
*Not a HASH reference at SL/IS.pm line 385.
**Attempt to free unreferenced scalar: SV 0x87087c0, Perl interpreter:
0x817b008 at SL/IS.pm line 385.*

This occurs whenever trying to print an invoice either as PDF or HTML.

Environment is:
Debian
Perl 5.10.0-19
SQL Ledger 2.6.27
Latex installed.

All had been working in the past but assume some Perl upgrade caused probs?
Any solution suggestions appreciated.  Found a couple f references to this
last year but no solution.
