kdesudo "No command arguments supplied!" information messages

[Murz]

I have installed a fresh Kubuntu 9.10 Alpha4 from alternate cd (to the mdraid disk) and after that installs kde via "aptitude install kubuntu-desktop".
Always work's fine but each time after restart and sometimes at work (changing some settings in kde config, doing other things) it shows the window:
Title: Information - KdeSudo
No command arguments supplied!
Usage: kdesudo [-u <runas>] <command>
KdeSudo will now exit...
And OK button.
When I press OK the window is disappear and nothing happens.

What does this window mean and how I can detect and solve this problem?

Jonathan Thomas, this bug is not a duplicate of bug #250330 because it isn't exists in Kubuntu 9.04, bu exists only in Kubuntu 9.10 alpha 4.
And this messages shows automatically without run the kdesudo and other actions manually.
If I starts kdesudo manually, for example "kdesudo kate", it works.
I think this is not a kdesudo bug, but bug in kde-workspace or ubuntu kde addons, because, I think, some program try to start other program but miss the arguments for kdesudo...
And I can't find the way to detect which process shows try to run automatically kdesudo and shows this message.
Please remove the duplicate of bug.

I can confirm what Murz says that this is not a duplicate. It still occurs in the released 9.10.

I'm getting the same error, but in 11.04. Any ideas on how to fix this?
