Old crashdb.conf.d entries with bug_pattern_base (even if it is None) cause crash in apport.

Thank you for taking the time to report this crash and helping to make Ubuntu better. This particular crash has already been reported and is a duplicate of bug #625259, so is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Please continue to report any other bugs you may find.

Removing the duplicate status since it looks like a recent move to a single bugpatterns.xml could have caused it.
Investigating...

Hm, at some point in time db becomes
name = ubuntuone
db = {'project': 'ubuntuone-client', 'impl': 'launchpad', 'bug_pattern_base': None}

Ok, it turns out here's what gets bundled with ubuntuone:
ubuntuone = {
        'impl' : 'launchpad',
        'project' : 'ubuntuone-client',
        'bug_pattern_base' : None,
}

in ubuntuone-client-crashdb.conf

Since we are using bug_pattern_base, we break apport reporting. Reassigning to myself.

As far as I see this will also affect bug patterns for indicator-applet and indicator-appmenu since they also provide /etc/crashdb.conf.d/ entries.

On a second thought this looks like a bug in apport that changing crashdb.conf.d entries won't be able to fix. It looks like conf.d entries will need to provide bug_pattern_urls which should not be required in case main bugpatterns.xml is used.

Indeed. I'm going to fix apport so that it (1) doesn't crash on an absent 'bug_pattern_url' (and just doesn't use bug patterns in that case), and (2) falls back to the default bug pattern URL for custom crashdb.conf.d/ files.

I keep the indicator-applet and ubuntuone-client tasks open for removing the now obsolete bug_pattern_base entry from their configuration, but that's now low priority.

Fixed in apport trunk in r1866 and r1867.

This bug was fixed in the package apport - 1.19-0ubuntu3

---------------
apport (1.19-0ubuntu3) natty; urgency=low

  * Merge fixes from trunk:
    - apport-retrace: Intercept SystemErrors from ill-formed gzip attachments
      as well.
    - Fix crash if crash database configuration does not specify a
      bug_pattern_url. Just assume None. (LP: #731526)
    - If a custom crash database does not specify a bug_pattern_url, fall back
      to using the default database's. (LP: #731526)
