bzr crashed with IOError: Broken pipe in report_exception(), trying to write 'bzr: interrupted'

[John O'Brien]

Binary package hint: bzr

I rebooted after a dist-upgrade and got this error. Very strange.

IOError: [Errno 32] Broken pipe

[Andrew Bennetts (spiv)]

I guess if stderr has already been closed then report_exception should just catch and ignore broken pipe errors when trying to write to it. There's not much else we can usefully do.
