Bug Description

Running bzr selftest in Ubuntu 12.10, the following test seems to fail on every machine I have tried it on, always with the following error:

FAIL: bzrlib.tests.test_crash.TestApportReporting.test_apport_report
_StringException: Empty attachments:

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/bzrlib/tests/", line 57, in test_apport_report
  File "/usr/lib/python2.7/dist-packages/bzrlib/", line 127, in report_bug_to_apport
    crash_filename = _write_apport_report_to_file(exc_info)
  File "/usr/lib/python2.7/dist-packages/bzrlib/", line 173, in _write_apport_report_to_file

Ran 27987 tests in 293.810s

FAILED (failures=1, known_failure_count=59)
2763 tests skipped

I created an lxc container (sudo lxc-create -t ubuntu -n bzr-test) and ran bzr selftest in there. It skips test_crash, due to the missing dependencies, but every test that is run passes happily. After installing apport and python-apport, test_crash runs, and fails. The included error report is from bzr selftest run inside that lxc container.

Quickest way to reproduce this is the following:
bzr selftest --one -s bzrlib.tests.test_crash

Oh, actually I'm seeing two issues here. Apport wants a file opened in binary mode for pr.write, but it was also failing in my lxc container for a _second_ reason:
pr['Locale'] = os.environ.get('LANG')
That causes a crash in a minimal environment, with the LANG variable unset, because apparently python-apport's Report class doesn't like when we set an empty value.

There are a 4 other failing tests, with the qbzr and builddeb plugins, but at least those ones aren't in core bzr :)
