           Summary: corrupt MARC record can abort import batch commit
           Product: Koha
           Version: HEAD

            Status: NEW

A MARC record that is corrupt because it has non-UTF8 control characters in the
leader can be successfully staged, but a commit operation (e.g.,
commit_biblios_file.pl) can fail because the MARCXML generated by the staging
operation is invalid.

The error message associated with the crash is:

substr outside of string at /usr/local/share/perl/5.8.8/MARC/Record.pm line
554.

This is a multi-part bug:

[1] MARC::File::XML should not emit a UTF-8 MARC record that isn't actually
valid UTF-8.
[2] This kind of record corruption should be detected during staging.
[3] $marc->warnings() should be checked; if it includes a warn that the leader
is not of the correct length, the record should be considered corrupt.
