Created attachment 83008

A simple patch that fixed the issue.

After segmentation faults in inkscape and rsvg_convert, the backtrace points to
strlen called from write_used_glyphs in cairo.

Please see https://bugzilla.redhat.com/show_bug.cgi?id=957009 for the bug
reported to Fedora.

In some cases _cairo_winansi_to_glyphname can return null, so write_used_glyphs
should check that.

Attached a naive patch that fixed the problem.
