[Bug 1229856] Re: kernel oops results in apport-gtk launching for every .crash file

[Brian Murray]

Looking at the upstart user job log files we see:

 $ cat ~/.cache/upstart/update-notifier-crash-_var_crash__usr_lib_firefox_firefox.1000.crash.log
Tue Sep 24 09:52:46 PDT 2013 crash report /var/crash/_usr_lib_firefox_firefox.1000.crash detected
ubuntuone-syncdaemon

 $ cat update-notifier-crash-_var_crash__usr_bin_xeyes.1000.crash.log
Tue Sep 24 09:52:46 PDT 2013 crash report /var/crash/_usr_bin_xeyes.1000.crash detected
ubuntuone-syncdaemon

Most of the other crash.log files look the same except for ubuntuone-
syncdaemon.

 $ zcat update-notifier-crash-_var_crash__usr_lib_ubuntuone-client_ubuntuone-syncdaemon.1000.crash.log.1.gz
Tue Sep 24 09:48:04 PDT 2013 crash report /var/crash/_usr_lib_ubuntuone-client_ubuntuone-syncdaemon.1000.crash detected
ubuntuone-syncdaemon

(apport-gtk:2718): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:1605:38: '' is not a valid color name
Tue Sep 24 09:52:46 PDT 2013 crash report /var/crash/_usr_lib_ubuntuone-client_ubuntuone-syncdaemon.1000.crash detected
ubuntuone-syncdaemon

One is from before the reboot after the kernel oops and the other is
after it.

The contents of the linux crash log file are also interesting:

 $ cat update-notifier-crash-_var_crash_linux-image-3.9.0-030900-generic.229283.crash.log
Tue Sep 24 09:52:46 PDT 2013 crash report /var/crash/linux-image-3.9.0-030900-generic.229283.crash detected
ubuntuone-syncdaemon

so the linux*.crash file was detected but it remains unmodified for some
reason.

Title:
  kernel oops results in apport-gtk launching for every .crash file

Status in “update-notifier” package in Ubuntu:
  New

Bug description:
  I've been testing multiple different kernels for bug 1218004, as a
  part of this process my system frequently experiences a kernel oops.
  Only occasionally, is a kernel oops crash file created for these
  crashes.  This particular time the following happened:

  Sep 24 09:47:42 localhost kernel: [  330.255893] ubuntuone-syncd[2596]: segfault at 20 ip 00007f1e907d3300 sp 00007fff91549050 error 6 in libc-2.17.so[7f1e90752000+1bd000]
  Sep 24 09:47:54 localhost kernel: [  341.887110] BUG: unable to handle kernel NULL pointer dereference at 0000000000000070
  Sep 24 09:47:54 localhost kernel: [  341.887197] IP: [<ffffffff811fbfd7>] show_vfsmnt+0x37/0x150
  Sep 24 09:47:54 localhost kernel: [  341.887242] PGD 72b78067 PUD 6d306067 PMD 0 
  Sep 24 09:47:54 localhost kernel: [  341.887276] Oops: 0000 [#1] SMP 

  It looks like ubuntuone-syncd crashed and shortly after that I
  experienced a kernel oops.  Looking in /var/crash we can see the
  following:

   $ ls -lctr /var/crash/
  total 39532
  -rw-r----- 1 root     whoopsie     7141 Sep 18 10:10 linux-image-3.9.0-030900-generic.229283.crash
  -rw-r--r-- 1 bdmurray whoopsie        0 Sep 18 12:00 _usr_bin_xeyes.1000.upload
  -rw-r--r-- 1 bdmurray whoopsie        0 Sep 18 12:02 _usr_bin_d-feet.1000.upload

  -rw-r----- 1 bdmurray whoopsie   105043 Sep 24 09:53 _usr_lib_firefox_firefox.1000.crash
  -rw-r----- 1 bdmurray whoopsie  1770585 Sep 24 09:53 _usr_bin_xeyes.1000.crash
  ---------- 1 bdmurray whoopsie    50209 Sep 24 09:53 _usr_bin_gnome-session.1000.crash
  ---------- 1 bdmurray whoopsie   952256 Sep 24 09:53 _usr_bin_easystroke.1000.crash
  -rw-r----- 1 bdmurray whoopsie  3851246 Sep 24 09:53 _usr_bin_d-feet.1000.crash

  Something caused every crash file's modification time to change.  The
  end result of this being that on the next reboot I received an apport-
  gtk notification for every crash, even ones that I experienced some
  time ago and that have already been uploaded.  While this is an
  unlikely, it is rather annoying.
