Comment 39 for bug 445303

Only got this bug on amd64, the i386 are not affected. In update-manager and synaptic i cannot refresh the package list and got no download. The window still hang, the server test in both programs works well. Update with aptitude works well. After this happening more gksudo events like network-manager config are affected, nothing happens if the pass are entered.
The ppa policykit package did not help here.
