Hello and happy Easter!

I have a problem with the patronage card printing. I also described the problem in Bug 20077. I got a tip from Katrin to try the mailing list.

When I try to print the patron cards, the /usr/share/koha/intranet/cgi-bin/patroncards/create-pdf.pl does not finish and runs with 100% CPU load.

In plack-error.log I find the following lines:

Use of uninitialized value $batch_id in concatenation (.) or string at /usr/share/koha/intranet/cgi-bin/patroncards/create-pdf.pl line 68.

Use of uninitialized value in multiplication (*) at /usr/share/koha/lib/C4/Patroncards/Patroncard.pm line 239.

The problem first appeared in February 2018 after I started the Ubuntu updates. Unfortunately I don't remember what has been updated.

Unfortunately I am not able to print patron cards at the moment. It would be great if there was a solution for this soon.

Many greetings
