Bug Description

Binary package hint: metacity

When upgrading to metacity-, the new package installs without error but metacity does not run when you start X because it cannot find workspace names using gconf. To trigger this bug, create more than 16 workspaces before upgrading. The problem is that the metacity schema in /usr/share/gconf/schemas/metacity.schemas only has slots for 16 workspace names, but metacity lets you have up to 36 workspaces. The workaround is to manually edit the metacity.schemas file and add slots 17 - 36 under the key for /schemas/apps/metacity/workspace_names/name then run "gconf-schemas --register-all".

this also happens in clean install ...
1) add workspace switcher
2) add e.g. 20 workspaces - everything works like expected
3) restart
4) no metacity after login (no error message or something; just windows without borders)
5) "metacity --replace" gives same error as above

This one is still true for 10.10 amd64 . I just borked my workstation by adding "too much" workspaces (20).

Hi. Since this quite annoying bug was fixed upstream I decided to apply the patch to the package. Is it possible to get this into Natty? It's a quite annoying bug which can be triggered quite easily. Once broken it's probably not that easy for inexperienced users to fix their systems.
