I tried the patch using network-manager_0.8.1-4.debian.tar.gz network- manager_0.8.1.orig.tar.gz on testing/squeeze, and it works for me.
The patch applied with an offset of -2 lines on both hunks in system- settings/plugins/ifupdown/plugin.c. Then I compiled the package with "dpkg- buildpackage -b". I have installed the locally built packages, NetworkManager was started as a daemon and my wlan0 connection remained intact. I have attached the relevant bit of /var/log/daemon.log. To make the counter-test I have re-installed network-manager from packages.debian.org and the connection dropped immediately after the installation of the package. Thanks for looking into this.
