Comments:
I downloaded the TKWeather application, and noticed this problem...This
    application was not save the GIF image correctly, thus this problem
    occured...I have since fixed the application by incorporating the
    fconfigure to set the file i/o to binary:

ReproducibleScript:
load an image, in my case a bad (corrupted) GIF image, causes the Tcl
    interperter to crash...
    
    I'm running on a WinNT 4.0 workstation

ObservedBehavior:
the interperter crashes

DesiredBehavior:
the image loader should validate the image and if fails then returns
    gracefully, instead of crashing...



We need the actual bad image to test this bug.  8.3 will have
an objectified image command, although the underlying internals
aren't too much different, so it might still be susceptible.
