Bug Description

Binary package hint: apport

Brian Murray pointed out bug 418297 to me since I touched odt2txt last. As it turns out, these crashes are from tracker setting soft RLIMITs on CPU time (line 143, src/libtracker-common/tracker-os-dependant-unix.c), and odt2txt was hitting them. This kind of thing should probably be considered "normal" behavior, and doesn't really need a crash report. Either these signals should be ignored, or a new kind of crash should be reported that includes the RLIMIT details as well as a process ancestry to find who set the limits (and this doesn't seem like a general-purpose action really).

Branch attached to ignore the signals. Simple reproducer (note that bash ignores SIGXCPU by default):

$ bash
$ ulimit -St 5
$ trap "echo XCPU >&2; exit 1" 24
$ while :; do echo monkey >/dev/null; done
XCPU
$ echo $?
1

This bug was fixed in the package apport - 1.10-0ubuntu1

---------------
apport (1.10-0ubuntu1) lucid; urgency=low

  * New upstream release:
    - Add a mode for updating an existing problem report to ui.py
      (-u/--update). This is similar to the Ubuntu specific "apport-collect"
      tool, but implemented the right way now: In particular, this has access
      to the UI and thus can use interactive hooks (LP: #385811) and show you
      what is being sent for confirmation/cancelling (LP: #371827)

    - apport-bug: If invoked as "apport-collect" or "apport-update-bug" (i. e.
      through a symlink), run apport in update mode (-u <number>). This
      provides a convenient no-options command line program. Please note that
      setup.py does not currently install such a symlink. Update the
      apport-bug manpage accordingly.

    - launchpad.py: Use new login_with() to clean up code, and specify allowed
      access levels (WRITE_PRIVATE is the only sensible one anyway).
      (LP: #410205)

    - New hookutils functions:
      + xsession_errors (match lines from ~/.xsession-errors)
      + shared_libraries (determine which libraries a binary links with)
      + links_with_shared_library (test if a binary links with a particular
        library)

    - New CrashDatabase API: get_affected_packages(), can_update(), is_reporter()

    - Rename CrashDatabase.update() to update_traces().

    - Add CrashDatabase.update() for adding all new fields of a report. This is
      primarily useful for collecting local standard and package hook data for an
      already existing bug report which was not filed through Apport. This checks
      can_update()/is_reporter() if the user is eligible for updating that
      particular bug. (LP: #485880)

    - Ignore SIGXCPU and SIGXFSZ; thanks to Kees Cook. (LP: #498074)

    - launchpad.py: Do not mark non-Ubuntu bugs as needs-retrace, since there is
      no retracer right now. (LP: #489794)

    - packaging-apt-dpkg.py, install_retracing_packages(): Do not crash on
      malformed Dependencies.txt lines. (LP: #441709)

    - use-local: Fix for new source tree location of "apport" binary.

  * Drop debian/local/apport-collect{,.1} and install symlinks for apport-bug
    instead.
  * data/general-hooks/ubuntu.py: Do not report "corrupted filesystem tarfile"
    package errors. (LP: #320743)
  * data/general-hooks/ubuntu.py: Report "package ... is already installed and
    configured" errors against dpkg, not the package that failed. (LP: #467688)
