Thank you for your bug report.

Martin, any clue if that's something nautilus does wrong or an apport issue?

It is a bug in the nautilus package hook: Any file which is not packaged (I have a /usr/lib/nautilus/extensions-2.0/ causes apport.packaging.get_file_package() to return None, which package_versions() doesn't digest.

However, I'll just make package_versions() get along with this.

This bug was fixed in the package apport - 1.12.1-0ubuntu1

apport (1.12.1-0ubuntu1) lucid; urgency=low

  [ Martin Pitt ]
  * New upstream bug fix release:
    - Do not keep escalating bugs, just escalate at the 10th
    - Improve error message if a symptom script did not determine a package
      name. (LP: #503834)
    - general-hooks/ Fix crash on libGL check with empty
    - Review and clean up usage of chmod(). This fixes a small race condition
      in the Python exception hook where a local attacker could read the
      information from another user's crash report. (LP: #516029)
    - hookutils, package_versions(): Ignore "None" packages, for more robust
      package hooks. (LP: #518295)
  * debian/apport.install: Actually install the bash completion file.
    (LP: #218933)
  * Bump Standards-Version to 3.8.4 (no changes necessary).

  [ Leann Ogasawara ]
  * Tag kernel bugs which utilize a driver from staging. Also
    provide the list of staging drivers in use. Prefix suspend/resume bug
    titles with "[STAGING]" if a staging driver was being used.
    (LP: #524174, #524167)
