incomplete crash files getting uploaded to the error tracker

Looking at apport's code I don't see anywhere the report file is written to more than once.

For what it is worth the examples are both python tracebacks and not coredumps.

I mean anywhere the .upload file is written two times.

I've managed to recreate this issue, well the uploading of the incomplete crash report at least, by doing the following.

1) in a terminal run 'sudo chmod 600 /etc/apt/sources.list'
2) run 'update-manager'
3) observe a crash and click "Leave Closed" on the crash notification dialog
4) confirm that there is in /var/crash/ a .upload and .uploaded file for the update-manager crash

If you inspect the update-manager crash file you'll notice it is missing Dependencies and DistroRelease so the additional apport data collection was never done.

The test case I've indicated might be a bad example as apport will also want to use apt, however the apport dialog contains information (revealed after clicking "Show Details") that doesn't get written to the report.

UnreportableReason: E: Opening /etc/apt/sources.list
DistroRelease: Ubuntu 14.04

So there is still something wrong in apport's code.

I'd tracked the update-manager case down to the following in apport/ui.py:

    try:
        report.add_package_info(package)
    except ValueError:
        # this happens if we are collecting information on an uninstalled
        # package
        if not ignore_uninstalled:
            raise
    except SystemError as e:
        report['UnreportableReason'] = excstr(e)
        return

We are returning from thread_collect_info() before we've written the collected information to the report. Removing the return works but then 'UnreportableReason' was changed to 'This package does not seem to be installed correctly'. I think this issue with /etc/apt/sources.list is likely a separate bug (than the menulibre examples in the description), so I'll open a separate bug for it.

This may be a duplicate of bug 1512902, although it seems unlikely if the same crash report was submitted later.
