[FWTools] libtiff assertion failure

Having an annoying problem with Linux FWTools. I have some GeoTIFFs
that I'm trying to use with MapServer's shp2img, but it dies with the
tif_dirread.c:4670: TIFFFetchNormalTag: Assertion `0' failed.
Actually, opening the file in OpenEV or even running gdalinfo on the
file produces the same error, and the program dies.
Interestingly, I ran gdalinfo.exe from the Windows version of FWTools,
and it worked fine, but gave the following warning:
Warning 1: TIFFFetchNormalTag:ASCII value for tag "Software" does not
end in null byte
...so I'm guessing this is what's causing the problem under Linux. The
files were created by jNexradExplorer, so I'll email the author to see
if he can fix it at that end. But is it possible to have the tools
warn instead of die on this error? Or, is there something I can do to
fix the files as a workaround (a way to strip or rewrite the
"Software" tag, perhaps)? This is all part of a scripted batch job, so
I'd need to be able to repeat it from a script.
