I tested with Debian Sid, but there the program started without any error messages. So it looks like this might be an Ubuntu-specific issue.
Since the error message mentions an undefined symbol I tried rebuilding the hocr package on my Vivid system to see whether that would help, but I still got the same error message. ** Tags added: trusty vivid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1403166 Title: hocr python error at startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hocr/+bug/1403166/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
