dbus.proxies:Introspect error when cleaning up prevents clean up action

Marking as Critical since it renders the package completely unusable.

Could bug #665740 also be related to this.

Happens also in gnome-keyboard-properties in Natty when you try to apply globally your changes (try running that from the console, and look for the output):

Caught remote method exception org.freedesktop.PolicyKit1.Error.Failed: Error getting subject: Error parsing unix-process subject: Value for key `start-time' found but is of type i and type t was expected

Same here, can´t change my keyboard layout!

Bug 665740 is a different problem.

It's not possible to change keyboard layout or network proxy system-wide because of this.

Still investigating, but I suspect this is a bug in polkit since:

1) the same code for CJ works in maverick
2) this bug is affecting multiple different packages

I'm guessing that the type for start-time got erroneously changed from uint64 to string. This page still describes start-time's time to be the former:

http://hal.freedesktop.org/docs/polkit/eggdbus-interface-org.freedesktop.PolicyKit1.Authority.html

The problem is that automatic type conversion of 0 gives you a UInt32(0) under Natty, where a UInt64(0) is expected. You have to be explicit about the type conversion for start-time. I have a patch for computer-janitor that I'll propose momentarily.

This bug was fixed in the package computer-janitor - 2.0.4-0ubuntu3

---------------
computer-janitor (2.0.4-0ubuntu3) natty; urgency=low

  * debian/control: Add explicit dependency on dbus since depending on
    python-dbus does not yield an implicit dependency on dbus. (LP: #665740)
  * computerjanitord/authenticator.py: Explicitly convert start-time to a
    UInt64(0). Under Natty, implicit conversion uses a UInt32 which does
    not match the CheckAuthorization signature. (LP: #676488)

I can not reproduce this bug anymore (even on proxy settings or keyboard configuration).

Can someone confirm that this bug is fixed?

It's definitely fixed for C-J. I don't know if the other packages were
patched the same way, or whether some change in python-dbus was made to fix it
for all clients.

Almost sure that is fixed. Setting it as so.

Still not resolved in Maverick.

what can I do?

thank you

Fixed? Not for me:

Can we please re-open?

I think that's bug 715707.
