Odd errors on vdsm_unit_tests

Jenkins used to send email notifications about unit tests failures to vdsm-patches(a)lists.fedorahosted.org at least until March 20. Come to think of it, the emails seized to have content on March 5. Now they are not sent at all. Beyond this, we have a very odd non-deterministic failure http://jenkins.ovirt.org/job/vdsm_unit_tests_gerrit/1976/console (except below). Could the test be run with an unusual locale? Does anybody have another idea? Could someone (Giuseppe? David?) log into this fedora18-vm01 slave and try to reproduce the issue from the command line? Regards, Dan. ====================================================================== ERROR: test_deviceCustomProperties (hooksTests.TestHooks) ---------------------------------------------------------------------- Traceback (most recent call last): File "/jenkins-workspaces/vdsm_unit_tests_gerrit/tests/hooksTests.py", line 125, in test_deviceCustomProperties params={'customProperty': ' rocks!'}) File "/jenkins-workspaces/vdsm_unit_tests_gerrit/vdsm/hooks.py", line 72, in _runHooksDir scriptenv[k] = unicode(v).encode('utf-8') UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 7: ordinal not in range(128) ====================================================================== ERROR: test_runHooksDir (hooksTests.TestHooks) ---------------------------------------------------------------------- Traceback (most recent call last): File "/jenkins-workspaces/vdsm_unit_tests_gerrit/tests/hooksTests.py", line 72, in test_runHooksDir res = hooks._runHooksDir(DOMXML, dirName) File "/jenkins-workspaces/vdsm_unit_tests_gerrit/vdsm/hooks.py", line 72, in _runHooksDir scriptenv[k] = unicode(v).encode('utf-8') UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 7: ordinal not in range(128)
