Bug Description

Binary package hint: apport

I just attempted to report a bug against linux using "ubuntu-bug linux" when I got the following error:

***

Testing the upstream kernel can help isolate issues in Ubuntu kernel patches, discover a bug is fixed upstream, or confirm the issue exists upstream. It would be great if you could test with the upstream kernel and let us know your results by posting a comment in the bug report. For information on testing the upstream kernel, refer to https://wiki.ubuntu.com/KernelTeam/MainlineBuilds

It looks like this bug affects systems that do not have a file: /proc/asound/cards. This is the case for many server deployments. The specific section of code in /usr/lib/python2.6/dist-packages/apport/hookutils.py is this for loop:

for line in open('/proc/asound/cards'):
        if ']:' in line:
            fields = line.lstrip().split()
            cards.append(int(fields[0]))

Maybe add a test for that file first?

This bug was fixed in the package apport - 1.17-0ubuntu1

---------------
apport (1.17-0ubuntu1) natty; urgency=low

  * New upstream release:
    - Better standard bug titles for Python crashes. Thanks Matt Zimmerman!
      (LP: #681574)
    - Add handler for uncaught Java exceptions. There is no integration for
      automatically intercepting all Java crashes yet, see java/README.
      Thanks Matt Zimmerman! (LP: #548877)
    - GTK frontend: Require GTK 3.0.
    - launchpad.py: Default to "production" instance, not "edge", since edge
      is obsolete now.
    - hookutils.py, attach_alsa(): Fix crash if /proc/asound/cards does not
      exist. (LP: #626215)
    - ui.py, format_filesize(): Fix to work with stricter locale.format() in
      Python 2.7. (LP: #688535). While we are at it, also change it to use
      base-10 units.
    - hookutils.py, package_versions(): Always include all requested package
      names even if they're unknown to us. Thanks Matt Zimmerman!
      (LP: #695188)
    - launchpad.py: When updating a bug, also add new tags. Thanks Brian
      Murray!
  * debian/apport.install: Install Java crash handler in
    /usr/share/apport/apport.jar.
  * debian/control: Add Java build dependency so that the Java crash handler
    will be built.

Does anybody have any thoughts about whether or not this should be fixed in Lucid? Its fairly easy to work around by commenting out 'attach_alsa(report') in /usr/share/apport/package-hooks/source_linux.py if necessary.
