Bug Description
Hello,
unrtf throws a coredump on some rtfs.
Ubuntu-Release: Ubuntu 14.04 LTS
Package: unrtf 0.21.5-1 (amd64)
I attach a test.rtf to reproduce the bug and a patch that fixes this bug.
But: this is just a PoC fix! It checks if the result of word_string is not null before the data is accessed (in the \\author section). Since word_string is used many more times in convert.c, every result should be checked.
