Found two bugs in this software.
The first one untaints the ocr_path_bin entries in the config, so the search path algorithm works again (you don't have to specify the helper application location).
The second one fixes a problem with an uninitialized variable if PDF scanning is disabled.
Please add this patches to the ebuild in portage.
