I can't establish any VPN-connections via NetworkManager anymore. Fortunately, I was able to use my university's vpnc via wlan to go online (manually set up vpnc via terminal).
And fortunately, I did my updates step by step this morning - did a reboot after each update and checked if everything was still working. So I can say, that this behaviour is due to these updates:
Mar 29 11:12:29 Updated: 1:NetworkManager-glib-0.8.997-6.git20110328.fc15.x86_64

Well, I can't open NetworkManager settings anymore and if I try to connect to a VPN, I get the error, that vpn-service could not be started.
Unfortunately, yum doesn't want to downgrade NetworkManager-openvpn, NetworkManager-vpnc, NetworkManager-openconnect, geoclue and NetworkManager-pptp. I have:
# yum downgrade geoclue
Loaded plugins: langpacks, presto, refresh-packagekit
Setting up Downgrade Process
Only Upgrade available on package: geoclue-0.12.0-7.fc15.x86_64
Nothing to do
(same with other packages mentioned above)

Okay, it seems to be related to the control-center* updates. I updated control-center now and have working "network settings" and OpenVPN-connections again. PPTP still states "failed to connect", but this might be related to something else...
My problem belongs to a much bigger issue: In "network settings" I may not change anything anymore. Adding VPN connections simply does nothing (not even an error message). Changing existing VPN preferences sometimes changes nothing and sometimes creates a second VPN connection with the same name. Furthermore pptp does not work, because the password has been changed to (null).
EDIT as of May 19:
Updates seem to have solved this quite a time ago...
