I had a blown installation due to the new kadmin patch which is failing on F21 (https://fedorahosted.org/freeipa/ticket/4914).
When I went to uninstall it failed in destroy_private_ccache() due to path being None. Unfortunately I lost the uninstall log when I was finally successful, so no backtrace.
My fix was:
if path and os.path.exists(path): os.remove(path)
