Upgrading libnl from 3.2.27 to 3.2.28 breaks internet connection

Hi

The recent minor version upgrade of libnl to 3.2.28 broke my wireless connection (wifi through networkmanager+wpa_supplicant+dhclient).
NetworkManager simply reports normal connection (and no errors/warnings are written into the journal or other logs), but all IP addresses are not accessible (except some local things, like the gateway), and no DNS of course. Tested only on wifi, so wired or 3G may still work.

By trial and error (downgrading all networking-related packages one by one) I found that rolling back just libnl is sufficient to restore normal wifi work.

Be cautious.

There's no problem for me in over 2 weeks since the update and an update which breaks networking would be spotted and reported quite quickly (there are no bug reports).  What network card do you use etc?
