Please allow empty messages without reporting an error.
IRC sometimes sends empty lines, so I don't think it would be good if
this normal behavior would be reported as an error in popup
notifications. I'd like to modify the behavior as follows:
1. only show popup notification on non-null non-empty message
2. log error if message is null.
3. do nothing if message is empty.
