Description of problem:
The second level, "Briefcase Message", forces a save and reload which causes the
game to crash with the following error message:

main.cpp:117: ERROR script failure;
error='/usr/share/games/fillets-ng/script/share/Pickle.lua:81: attempt to call a
table value
stack traceback:
        /usr/share/games/fillets-ng/script/share/Pickle.lua:81: in function
`unpickle_table'
        ...sr/share/games/fillets-ng/script/share/prog_save.lua:29: in function
`script_loadState'
        [string "script_loadState()"]:1: in main chunk'
Path.cpp:44: INFO creating path; path='/home/wart/.fillets-ng/script/options.lua'

Version-Release number of selected component (if applicable):
fillets-ng-0.7.3-5.fc6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Remove the ~/.fillets-ng directory to start fresh
2. Open a terminal and run 'fillets'
3. Work your way to level 2 "Briefcase Message"
4. Lift the pipe and move the nut to enter the workshop.
5. Let the game run on its own while it shows you tips in the workshop.  This
will trigger an automatic save, then an automatic reload once the level restarts
itself.
  
Actual results:
The game reloads and exits with the error message above once the fish reenter
the workshop.

Expected results:
The game lets the player continue after the level has restarted from the save point.

Additional info:
I've tried manually saving and reloading at various points on this level, but
still get the same results.

I see this problem on both FC6-i386 and FC6-x86_64, but not on FC5-i386.
