New bash 3.1-1 from unstable causes remaster script to fail

[tr]

Still problems. Now everything else works but not making a new remaster:

tapsa@linux:~$ sudo knoppix-remaster /mnt/hda16/remaster/
/usr/bin/knoppix-remaster: line 67: bad substitution: no closing `)' in REMASTER_NEEDED_SIZE=$[(df /cdrom /KNOPPIX | awk '{ N+=$3 } END { N+=(500000*0); print N }')*115)/100
                REMASTER_HAVE_SIZE=$(df $REMASTER_CHOICE  | awk '{ print $4 }' | tail -n1 ]

Sorry, but I'm not a developer myself and don't know how to fix this. This error message comes with new bash, so it need to be corrected. Perhaps it's time to ask Fabian Franz to do a new updated remaster script.
