Bug Description

Binary package hint: dpkg

apt-get dist-upgrade took a long time to complete on yesterday's bzip2 update (and other). apt-get dist-upgrade appeared to end up normally (no error in the terminal, I did no checked the return code). This morning, looking at /var/log/messages, I found some "call trace" logs for dpkg. For examples: Sep 20 17:52:25 saruman kernel: [13560.828370] dpkg D 00002553 0 14537 14465 0x00000000
