Comment 3 for bug 1000583

It appears that fix was made in 5.5.3 version:

2011-09-06 Sam Varshavchik <email address hidden>
        * rfc2045/reformime.c (main2): Fixed segfault on some arches from an
        initial null given to strtok.

change from:

mimesection = strtok(section,",")

to:

mimesection = section ? strtok(section, ","):NULL;
