test failure TestCheckwatchesWithSyncableGnomeProducts.test_bug_496988

This test consistently fails when PQM runs the test (merging into production-devel). It is fine in my locale environment. I disabled the test by renaming it: TestCheckwatchesWithSyncableGnomeProducts XXXtest_bug_496988

Error in test lp.bugs.scripts.tests.test_checkwatches.TestCheckwatchesWithSyncableGnomeProducts.test_bug_496988
