Bug Description

FIrefox is creating empty crash reports due to https://wiki.ubuntu.com/SecurityTeam/Roadmap/KernelHardening#PTRACE%20Protection and happily sending these to Mozilla. One such example is http://crash-stats.mozilla.com/report/pending/48dcb9bd-5e97-4c45-ab05-757642100823

This bug was fixed in the package firefox - 3.6.9+build1+nobinonly-0ubuntu1

---------------
firefox (3.6.9+build1+nobinonly-0ubuntu1) maverick; urgency=low

  * New upstream release v3.6.9 build1 (FIREFOX_3_6_9_BUILD1)

  * Drop patch after landing of (bmo: 569836) aka Build fails on
    Fedora Core 13
    - remove debian/patches/ftbfs_crashreporter.patch
    - update debian/patches/series
  * Don't suggest the transitional kmozillahelper now we've branched
    for Maverick. This stops it from being displayed as an addon
    for Firefox in software-center
    - update debian/control
  * Don't suggest the transitional latex-xft-fonts. Use ttf-lyx
    instead
    - update debian/control
  * Fix LP: #623509 - Firefox is creating empty crash reports due to
    kernel ptrace hardening
    - add debian/patches/bz591331_att469858_breakpad_allow_ptrace.patch
    - update debian/patches/series
  * Build with MOZILLA_OFFICIAL=1 again and in turn, enable the crashreporter
    - update debian/rules
  * Really fix LP: #605336 - "Report Broken Web Site" option missing - make
    sure that we install the reporter chrome
    - update debian/rules

Could this also be affecting FF 3.6.9 in Lucid? I have noticed a "Crash Reports" directory appearing now under the main "Firefox" one all the time now..

No, the ptrace restrictions only exist on Maverick kernels. The empty crash report directory is a completely normal part of the Firefox profile. This bug was referring to sending empty crash reports to Mozilla.
