Comment # 1 on bug 1137164 from Jonathan Kang

Please provide related logs as described below:

1. kill packagekitd
  - you can use "ps" to get the pid of packagekitd and kill it
2. run "/usr/lib/packagekitd -v > pk-logs" to start PackageKit manually
3. run gpk-update-viewer to update your system until it fails
4. attach pk-logs here
