Don't use :execute and incorrect escaping. The following should work:

    let &l:statusline='%!FunctionFromWhichIAmTryingToGetAStatusline('.string(a:1).')'

Function fnameescape() has other purpose and it must not be used to escape strings for statusline.

I am not sure how this would deal with some special characters though: those below 0x20 and %. They should not cause trouble AFAIK, but I may be wrong.
