Package: fontforge
Version: 0.0.20080429-1

If I try to use FontForge to convert the attached tiny .sfd file
into an SVG font, using the command line

  fontforge -lang=ff -c 'Open($1); Generate($2);' test.sfd test.svg

then fontforge terminates with a segfault, having opened test.svg
for writing but not written any data to it.

This occurs on a Debian Lenny machine on ordinary Intel x86.

Running it under valgrind reports (after a lot of errors in
PyObject_Free, which appear to be unrelated to the segfault inasmuch
as they also occur in runs of fontforge which complete successfully):

==28251==  Address 0x3f is not stack'd, malloc'd or (recently) free'd

which looks as if something has either trashed its stack or called
through a corrupted function pointer. I tried debugging it myself,
but was unable to reproduce the problem in a version of fontforge
built with debugging information.

Here are my installed version numbers of packages which are either
listed in fontforge's dependencies or which provide a shared library
listed by 'ldd fontforge':
