gksudo grabs cmdline arguments even if they appear after the called program (was: ubuntu-bug doesn't honor -w when called via gksudo)

[Guntbert Reiter]

When calling ubuntu-bug -w it shows a dialog ("After closing this message please click on an application window to report a problem about it.") and expects you to click on some window to determine the process/package against which the bug should be reported.
During a running upgrade I tried that and got: "that window doesn't belong to you" (correct, it was owned by root :-))
Calling gksudo ubuntu-bug -w results in the standard dialog ("what kind of problem do you want to report?") instead of the one initiated by the -w.

Steps to replicate:
1) call ubuntu-bug --- see the standard dialog
2) call ubuntu-bug -w --- see the "click" dialog
3) call gksudo ubuntu-bug -w --- see the standard dialog

btw: the attached logs seem to show a crash of apport, which is unrelated to this bug

The correct invocation is:

gksudo -- ubuntu-bug -w

Unfortunately it doesn't seem to be documented anywhere and the whole behavior looks like a gksu bug to me.

Sergey: How in the world did you find that? Anyway thx, I changed the bug's description accordingly.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
