[recoll-user] Some warnings on index update

With "recoll -c recoll.conf" and then "Update index" in the GUI that
opens I get several hundred warnings like:

:2:rcldoc::: HELPERNOTFOUND antiword
:2:../internfile/mh_exec.cpp:71:MimeHandlerExec: command status 0x100:
/usr/share/recoll/filters/rcldoc
:2:../internfile/internfile.cpp:406:FileInterner::internfile:
next_document error
:2:../internfile/internfile.cpp:488:FileInterner::internfile:
conversion ended with no doc
:2:../internfile/internfile.cpp:360:FileInterner::internfile: bad
stack size 0 !!
and so on.

What are they, do I need to be concerned, how can I fix them?

Regards,
Jernej
