Created attachment 3838 [details] [review] Patch
This patch has been obsoleted by the patch pushed for 5579 (in 3.4/3.5). However, it may still be of relevance for 3.2/3.3 installs.
Not sure this problem still exists in master. Patch still applies according to Julian, so we should try to reproduce the bug.
As Marcel said, the piece of code commented by this patch has been removed from Koha since 3.4, so I think we can close this bug.
Closing :)
