compiz crashed with SIGSEGV in nux::BaseWindow::GetInputWindowId() (when onboard is used)

[Veb]

SRU TEST CASE

1. Start a terminal from the launcher
2. Type 'onboard' <enter>
3. Type in the terminal, then click on keys on the onscreen keyboard
4. Verify that compiz does not crash

Just tried Upgrading from 11.04 to 11.10 beta. I expected failures.

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

[Sebastien Bacher (seb128)]

seems to happen when enabled "onscreen keyboard", i.e running onboard

[Sebastien Bacher (seb128)]

it's the same issue than bug #783439 it seems

[Chris Halse Rogers (raof)]

Hello Veb, or anyone else affected,

Accepted unity into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

This bug was fixed in the package unity - 4.28.0-0ubuntu2

---------------
unity (4.28.0-0ubuntu2) oneiric-proposed; urgency=low

  * Cherry-pick some additional fixes:
    - fix a regression where transparency is setup on the panel (LP: #830949)
    - the wrong commit causing a crash was revert. Revert the revert and
      revert the right guilty commit.

  * New upstream release.
    - don't segfault in geis_configuration_get_value() (lp: #850623)

      windows, opening any new window also incorrectly restores all
