Description of problem: Sometimes the dispatcher scripts in /etc/NetworkManager/dispatcher.d/ are not executed on service stop. This is on plain old ethernet with DHCP, let me know if you need more information.

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
With F12 and later, ethernet connections are not always torn down when NM stops. In fact, you should be able to do a 'service NetworkManager restart' and your network will no longer drop, because NM is able to take the connection over again when starting as long as it matches some saved network config in your ifcfg files. Is that what you're seeing here? It would be a bug if the dispatcher scripts were not run, *and* 'ifconfig eth0' showed the device had no IP address because NM tore it down.
The problem is with shutdown/reboot. The state stored by dispatcher scripts won't be removed and will be used on next start even in a completely different LAN.
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
