Package: transfig
Version: 1:3.2.5-alpha5-1
Severity: normal

I have ran across a case, where an image created in transfig fails to
export to anything. The dimensions are computed incorrectly (as large
negative numbers). If it's saved as postscript, ghostscript refuses to
interpret it. If it's saved as encapsulated postscript, an insanely big
box is shown. If it's saved as metapost source, metapost complains about
too large numbers. I attach the .fig that shows this problem (it's not
trivial and unfortunately I don't have time to test it more just now).

I also think, that this isn't a bug in transfig but in the program,
which created this .fig file.

As Jan didn't tell us how he created this .fig file, I'll close this
bug report now.  Feel free to reopen it and reassign it to the
program, which created this broken file.

Tschoeeeee
