[Bug 1237059] Re: dbus-daemon crashed with SIGSEGV

[Unit 193]

Ah, thanks for the pointers.

It's from kernel.org with custom config, also had tested the liquorix
kernel (http://liquorix.net/sources/)

During the upgrade, seems the saucy kernel was never pulled in, and as
I'm used to using my custom kernel all during Raring (issues with
-generic, checked randomly throughout the cycle) I may not have noticed
the generic kernel was still on 3.8.

In addition to that, seems the updated apparmor packages just came
through a few minutes ago, but guessing that's not the issue here.

Thanks for looking into this issue (and sorry about it!), do you know
when/if any patches will become part of upstream source?

Title:
  dbus-daemon crashed with SIGSEGV

Status in “dbus” package in Ubuntu:
  Invalid

Bug description:
  Upgraded from Raring to Saucy, fully updated system.
  dbus: 1.6.12-0ubuntu8

  Symptom: When you first load the desktop all seems normal except you
  are unable to launch applications.  After rebooting into a known good
  kernel, I got an apport window.  After sending the bug data, no
  browser appears, unable to open one, a terminal, or anything else.
  Switching to a TTY and restarting dbus will give you the terminal and
  browser, but the rest of the desktop is black and the border themes
  are the basic theme.  At this point the desktop is still unusable.

  Expected: Fully functional desktop.

  Steps taken to repair:
  1. Reboot into a known working kernel.
  2. Clearing out old config/cache.
  3. Reinstalling dbus (apt-get install --reinstall.)
  4. Downgrading dbus-x11, dbus, libdbus-1-dev, and libdbus-1-3 to 1.6.12-0ubuntu7.
  Only the last step had any effect.
