Title:
  Failing to import module breaks logging configurability and adds noise

Status in Python bindings for GObject:
  Fix Released
Status in “pygobject” package in Ubuntu:
  Fix Released
Status in “pygobject” source package in Trusty:
  Fix Released
Status in “pygobject” source package in Utopic:
  Fix Released

Bug description:
  When failing to import a module the gi.repository import.py module logs an error with `logging.error(..)` causing a logging handler to be added.
  This basically breaks the ability to configure the logging as it happens so early (i.e. at the import stage before an authors code is executed).

  To reproduce/Example:

  Run this script: http://pastebin.ubuntu.com/7698632/

  Expected outcome:
  No output to stdout or stderr and the text "log message" in the file "/tmp/example.log

  Actual outcome:
  No log file, and this text output to stderr:
    ERROR:root:Could not find any typelib for rubbish
    ERROR:root:log message

  Upstream fix:
  https://git.gnome.org/browse/pygobject/commit/?id=ac8b59e

  Regression potential:
  - The behaviour of raising ImportError on a nonexisting name does not change, but its text changes.
    Old: ImportError: cannot import name 'foo'
    New: ImportError: cannot import name foo, introspection typelib not found

    It's unlikely, however theoretically possible that a program matches
  on the precise error message.

  - It's theoretically possible that a program watches for the logged
  error message and ignores the ImportError. However, that would be
  extremely bad design, un-Pythonic and brittle as the logging
  format/destination can be changed arbitrarily.

  In summary the regression potential is very low.
