            Bug ID: 382133
           Summary: processing fails, caused by too long filename
           Product: digikam
           Version: 5.6.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: BatchQueueManager
          Assignee: digikam-devel at kde.org
          Reporter: mail at paul-neuwirth.nl
  Target Milestone: ---

There's obviously no check for too long filenames:
in my case processing works if there are no more than 4 steps. If a 5th step is
added the job will fail:

I assume this is caused by a too long filename:
~> touch
Batchtool-A12345-BatchTool-M29661-BatchTool-T29661-BatchTool-J29661-IMG_20170616_151042.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg
touch: cannot touch
'Batchtool-A12345-BatchTool-M29661-BatchTool-T29661-BatchTool-J29661-IMG_20170616_151042.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg.digikamtempfile.jpg':
File name too long

In this case filesystem is a NFS mount (v4, ext4 on host)

if you need any other data, i can try to deliver..
