I don't quite understand the code-path that leads to vfprintf() being
passed a NULL file-handle, but I see that we're calling
xmlCleanupParser() in both load_gpx_string_into_list() and
load_gpx_file_into_list(), and we should *never* be calling that,
because it basically unloads libxml2.
cf.:
http://0pointer.de/blog/projects/beware-of-xmlCleanupParser
http://lists.fedoraproject.org/pipermail/devel/2010-January/129143.html
And, sure enough--if I remove the calls to xmlCleanupParser(), the crash
appears to be fixed.
How did this ever work? :)
