apport-unpack crashed with IOError in <module>()

[miked]

Binary package hint: apport

firefox -g 2>&1 | tee ~/Desktop/gdb-firefox.log
... # some output
(gdb) run
... # run and reproduce crash
(gdb) bt full
... # full backtrace output
(gdb) thread apply all backtrace full
... # all threads full backtrace output
(gdb) quit

Now ~/Desktop/gdb-firefox.log will contain infos we need to initially process your crash bug. So, please attach that file to your bug report.

Copy and paste in a xterm the following command:

TMPDIR=$(mktemp -d)
apport-unpack /var/crash/_usr_lib_firefox_firefox-bin.1000.crash $TMPDIR
gdb -nx /usr/lib/firefox/firefox-bin -core $TMPDIR/CoreDump -ex 'backtrace full' -ex 'thread apply all backtrace full' -ex 'quit' 2>&1 | tee gdb.log
rm -fr $TMPDIR

That command will run gdb against the coredump file included in the crash report that was generated when firefox crashed.

Upload the resulting gdb.log to launchpad.

So, what exactly is the apport bug here?

BTW, instead of your rather complicated recipe you can install apport-retrace and get a gdb session for a .crash report with

  apport-retrace -g /path/to/crash/file

(see --help for other useful options, like fetching debug symbols, etc.)

[miked (miked11)]

not sure what the apport bug is here, I have moved to Hardy Heron Alpha 4 via fresh install from Live CD.
after trying a
root@HewittRand-desktop:~# sudo apt-get remove libselinux1 as suggested by someone to fix another constantly crashing program.
https://bugs.launchpad.net/ubuntu/+source/poker-network/+bug/95836/comments/11
nothing really worked on my computer after that, so I had to re-install, so I put the new Alpha 4 on here.
So I guess you can close the bug for now, and I will file if it happens again.
The complicated recipe is from here:
https://wiki.ubuntu.com/MozillaTeam/Bugs?action=show&redirect=DebuggingFirefox
but, thanks, I'll take note and try your suggestion in the future.

Added Info

[Martin Pitt (pitti)]

Ah, so I guess this is simply about throwing an exception rather than just an error message, and thus causing an apport report.

[Martin Pitt (pitti)]

Fixed in bzr head.

[Launchpad Janitor (janitor)]

This bug was fixed in the package apport - 0.103

---------------
apport (0.103) hardy; urgency=low

  * bin/apport-unpack: Print error messages instead of crashing for problems
    like nonexisting file names passed as arguments. (LP: #185273)
  * backends/packaging-apt-dpkg.py, is_distro_package(): Explicitly check site
    for "ppa", so that we do not automatically file bugs for PPA packages.
    This works around Soyuz bug LP #140412 for the time being.
  * apport/report.py: Add standard_title() test cases for Python crashes with
    a custom message, and a custom message with newlines. The latter
    reproduces LP #190947.
  * apport/report.py, standard_title(): Do not rely on a fixed position of the
    topmost function; use iteration and regular expression matching instead.
    (LP: #190947)
  * apport/ui.py, parse_argv(): Specify that --pid/-P argument must be an
    integer, to avoid exceptions when it's not. (LP: #193494)
  * apport/report.py: Use uname -srm, not -a, to hide the hostname. (part of
    LP #192786); also use os.uname() instead of calling the system program.
  * problem_report.py(): Make write() work for reports with CompressedValues.
    Add test case.
  * apport/ui.py: Add test case test_run_crash_anonymity() which asserts that
    the crash dump does not contain strings which can identify the user, such
    as the user name, login name, host name, and current directory.
  * apport/report.py: Add method anonymize() which replaces user specific
    strings with generic ones.
  * apport/ui.py, thread_collect_info(): Call anonymize() on the report.
    (LP: #192786)
  * bin/apport-retrace: Only update a bug report with new attachments if it is
    not a duplicate. (LP: #172792)
  * bin/apport-retrace: Print out proper error message instead of an exception
    if trying to do write operations to the bug tracker without specifying
    a cookie file. (LP: #146423)
