the reason for the error you are seeing is quite technical. Functions defined 
in modules can define a so-called "fixup function" for parameter 
preprocessing. Unfortunately, doing so can result in memory leaks and all 
sorts of other problems, so their usage is forbidden.

append_hf as well as remove_hf are such functions.

We have had numerous discussions on that topic, but unfortunately, the results 
have yet been limited. A lot of work needs to be invested to create matching 
functions for all fixup functions in the code.

You can disable the safety checks in the perl module using a "secret" 
parameter, but append_hf _will_ then result in problems sooner or later.

Sorry!
