I tried to get the exact file that caused the problem but it is already
destroyed by osstest.

A similar file:

http://logs.test-lab.xenproject.org/osstest/logs/115436/test-amd64-amd64-libvirt-pair/debian.guest.osstest.cfg

If you hexdump -C it, you can see the last character is 0a. Remove it and
feed the file into the converter.
