Bug Description
aa-logprof crashes if the log contains an (encoded) filename (for example, for a denied read access) and that filename contains a non-utf8 special character.
# cat audit.log-
type=AVC msg=audit(
(the original event/log was for a test profile - I changed it to klogd as an easy reproducer)
# aa-logprof -f audit.log-

This is easy to fix - just add errors='ignore' in open_file_read() in /usr/lib/
Nice if this could be added to the release as this is making logprof unusable if there's a single non-ASCII character in the logs.
