inputfile.last_line is not always available #1220
Description
LogFileParser expects its inputfile to support last_line, but this is only exposed by the custom FileWrapper class which is not used for all input types.
For a concrete example, any files parsed with --multi (which is common for Turbomole etc) are not wrapped, and LogFileParser will crash if a parsing error occurs.
