Description of problem:

The following traceback is received:

$ /usr/bin/mock --define="dist .el5.4.z" --print-root-path --uniqueext=XXXX
Traceback (most recent call last):
  File "/usr/sbin/mock", line 493, in 
    def do_buildsrpm(config_opts, chroot, options, args):
  File "/usr/sbin/mock", line 643, in main
    logging.getLogger("mockbuild.Root.state").handlers[0].setLevel(logging.WARNING)
IndexError: list index out of range


Version-Release number of selected component (if applicable):

mock-1.1.12-1

How reproducible:

Spuratic ...  I have no idea what is triggering this error.


Additional Info:

Obviously this isn't the greatest bit of information to resolve a 'bug' as the issue is likely something I am doing.  This is a build system where Mock is used on the backend and narrowing this down is proving difficult.  My request is simply to add a try/except to catch this error condition... something like:
