Distribution/Version: Slackware 10.2, Ubuntu 5.10, and SUSE 10.0

Create a new image (it doesn't appear to matter what size, but I used 420x300     
pixels). Select the "Text" tool and click on the image. Type some text; for my    
example, I used "the gimp" with Monospace font at size 40 px. Right click ->    
"Script-Fu" -> "Alpha to Logo" -> "Frosty". Click OK on the dialog. An error    
message pops up that says:    
    
Frost Message    
    
Error while executing    
(script-fu-frosty-logo-alpha 3 27 100 '(255 255 255))    
ERROR: Procedural database execution failed:    
    (gimp_edit_stroke 27)    
    
After clicking OK on the error message, not only does the script appear to    
have failed, but the entire image seems to be corrupted; I can no longer use    
the paint brush, undo, etc.   
   
Of course, the expected result is that the frosty script succeeds and that I   
can continue editing the image normally.   
   
It's important to note that this error happens almost all of the time, i.e.  
you almost certainly don't have to adhere to the above procedure to get the  
same error.  
  
I've found this bugs on all three Linux distros that I tested (Slackware,  
Ubuntu, and OpenSUSE), and it looks like it behaves precisely the same way on 
all of them. I haven't tested on any other operating systems.
