Jeremy Allison posted a patch which is said to fix the problem (http://lists.samba.org/archive/samba/2008-December/145677.html), however I cannot get it to compile. It fails with this error:
/usr/src/redhat/BUILD/samba-3.2.7/source/printing/print_cups.c:391: undefined reference to `close_all_print_db'

Patch for SWAT includes

This patch allows samba to compile with the patch from jeremy applied.
Comment 2 Jan Wenzel 2009-01-21 17:07:27 UTC 
With the patch from jeremy, it works for me. There are no panics anymore, printing is functional.

I've added a patch which allows samba to compile with the patch from jeremy applied.
