Does this stll happen with man-db-2.8.4? (In reply to Lars Wendler (Polynomial-C) from comment #1) > Does this stll happen with man-db-2.8.4? The first test on an other system with man-db-2.8.4 was succesful. 'man chown' worked.

After some digging the issue appears to be related to adding arguments to the command specified as PAGER. This worked fine with the deprecated man program, but man-db appears to really not like it.

Since this was with zsh I did another test with bash to confirm it is not shell related:
dragon@superbia ~ $ export PAGER="less -R"
dragon@superbia ~ $ echo $PAGER
less -R
dragon@superbia ~ $ man man
