Thanks a lot for this backtrace, this helps to locate the issue. It
seems that strcasecmp() is called with the second argument being NULL in
conf_get_tag_list() at at conffile.c:582. This would point to a bug in
the mount.nfs binaries.

However to fully confirm that, would it be possible to rerun the same
procedure after installing the libc6-dbg package? That should give more
details about what happens in strcasecmp().
