Locking the screen over lxpanel results in an error

[Removed by request]

I'm using Ubuntu 14.10 dev with lxde-common 0.5.0-4ubuntu4 and xscreensaver 5.26-1ubuntu1 and after upgrading xscreensaver from version 5.15 to 5.26 I'm noticing that locking over lxpanel does make some problems. Here is my panel entry:

Plugin {
    type = launchbar
    Config {
        Button {
            id=lxde-screenlock.desktop
        }
        Button {
            id=lxde-logout.desktop
        }
    }
}

If I'm now clicking the "id=lxde-screenlock.desktop" button nothing happens for several seconds and then xscreensaver locks the screen but shows the error message "couldn't grab pointer (AlreadyGrabbed)" and mouse movements doesn't popup the input fields anymore (but the keyboard is still recognized). Using "xscreensaver-command -lock" manually works fine.

I don't know where the problem lies, but it's not in xscreensaver. Something, possibly your panel, is holding the mouse grabbed. There is no way for xscreensaver to function if it can't get a mouse grab.
