ksmserver in kdebase-workspace 4:4.2.1a-0ubuntu3 forks off two KdeSudo processes without a command

[Sjors Gielen]

Binary package hint: kdebase-workspace

When I log in to my desktop, ksmserver forks off two KdeSudo processes without a command. Here's the pstree:

kdeinit4(4186)─┬─firefox(4394)─┬─{firefox}(4398)
[snip]
               ├─klauncher(4187)
               ├─ksmserver(4246)─┬─kdesudo(4344)───{kdesudo}(4347)
               │ ├─kdesudo(4352)───{kdesudo}(4354)
               │ ├─kwin(4248)───{kwin}(4249)
               │ └─{ksmserver}(4247)
[snip]

ie: kdeinit4 has forked off klauncher and ksmserver (and some others), and ksmserver forked off {ksmserver}, kwin, and two kdesudo processes. Here's the ps aux of the two kdesudo processes:

dazjorz 4344 0.0 0.9 311656 36212 ? Sl 10:05 0:00 kdesudo -session 101ab1a71d7102000123688744700000039750104_1236902616_246263
dazjorz 4352 0.0 0.9 311640 36192 ? Sl 10:05 0:00 kdesudo -session 101ab1a71d7102000123689639600000039750124_1236902616_246455

ie there's really no command listed. So when I log in, I get two popups saying:
No command arguments supplied!
Usage: kdesudo [-u <runas>] <command>
KdeSudo will now exit...
