[librecat-dev] Uninitialized value in concatenation

I am getting the following error message when processing a MARC-XML file
(converting it to JSON):

Use of uninitialized value in concatenation (.) or string at
/usr/local/share/perl/5.20.2/MARC/File/XML.pm line 399, <GEN0> chunk 311650.

What is this error about and how can I determine what input line / MARC
record is causing it?

Best regards,
