Subject: [PATCH] Fix regression in API caused by commit
 85400d8d6751071ef78f042d1efa72bdcf76cc0e   - The added optional parameter
 changes API and should default to None

    This utility call is used by for example requestbuilder package directly
    which breaks because it passes only one argument to the function as it
    used to be.
