I think he means give an example that would indicate how it was being
handled by those three places in the code.

Is that the only control=fakereject that you use in your entire
config? Are there any that do work with no problems? If yes, can you
show them here?

Also, I don't use quotes on my fakerejects and my \n's still work
properly. In testing, I was not able to make it segfault by adding
quotes to my config, but still I'd suggest as a first test that you
remove the quotes and see if it changes things.
