apport should filter username/homedir from JournalErrors.txt

[Steve Beattie]

apport in Ubuntu 15.04 and 15.10 includes in bug reports a file JournalErrors.txt that is the recorded output of the command 'journalctl -b --priority warning'. Apport also makes a best effort attempt to filter out information that bug reporters would like to keep private, like hostnames and usernames. However, the OneConf service is reporting log entries to syslog/journald that look like:

  Out 13 08:01:51 hostname com.ubuntu.OneConf[1120]: WARNING:oneconf.hosts:Error in loading other_hosts file: [Errno 2] No such file or directory: '/home/USERNAME/.cache/oneconf/7ae519bec912345a6925fb2d5448031b/other_hosts'

... only with the actual home directory (and by extension username) included in the path. Note that the hostname is correctly being filtered (and replaced with 'hostname'), so some filtering is being applied to this log file.

This worked for me on Wily.

I have the following version of apport installed: 2.19.1-0ubuntu2.

Brian, I've subscribed you to LP: #1505626 which has an example of this. Perhaps it affects vivid only?

[Steve Beattie (sbeattie)]

Brian, I've also subscribed you to LP: #1504864, in which the JournalErrors.txt contains some unfiltered zeitgeist entries as well as an email address.

No, I've found some Wily ones too. Searching my local cache of attachments it does seem to occur rather regularly.

The two sample bug reports are both about package installation failures, but the problem is not limited to those.
