some fontlint crashes

[Kevin Fenzi-4]

Greetings.

We are seeing some segfaults from fontlint when run over all the fonts
in the Fedora distribution. ;( (note though that it's just 5 fonts
providing the issue, of a very large number. ;)

Bugs:

Two of them seem to have the same weird stacktrace:

Core was generated by `/usr/bin/fontforge -lang=ff /usr/bin/fontlint usr/share/texmf/fonts/type1/urw/h'.
Program terminated with signal 11, Segmentation fault.
#0  getfilesize (fp=<value optimized out>) at Python/marshal.c:1026
1026 if (fstat(fileno(fp), &st) != 0)

Thread 1 (Thread 13246):
#0  getfilesize (fp=<value optimized out>) at Python/marshal.c:1026
        st =

Others have different ones:

The full traces are available on the above bugs.
Is there any further info I can provide to help track these issues down?
Happy to help do so.

thanks,

kevin
