This is similar to bug 5203. When you try to save a new or existing printer profile with a blank paper bin field the following error is generated and the profile is not saved: Software error: Can't call method "save" without a package or object reference at /home/liz/kohaclone/labels/label-edit-profile.pl line 72. For help, please send mail to the webmaster (webmaster@koha-deb), giving this error message and the time and date of the error.
Marking this as a dup of 5203 because the root cause is the same: no hardcoded defaults in the script. The fix for this, 5203, and an additionally related bug will be included in the fix for 5203. *** This bug has been marked as a duplicate of bug 5203 ***
