Compiz Scale plugin causes window decorator crash

[Ynot]

Binary package hint: unity

Unity uses the compiz scale plugin to select multiple instances of same application
Scale plugin seems to cause the window decorator to quit abruptly (leaving you with undecorated windows)

Steps to reproduce:

1. Ubuntu Unity desktop, complete with decorations
2. Open up 2 instances of nautilus (both maximised)
3. Open up a gnome terninal window (unmaximised) - this is our visual test case
4. On Unity dock - Double click nautilus icon
5. Scale plugin activated
6. Focus back on terminal window, and window has no decoration
7. "compiz --replace &" restores decoration

Can't reproduce this. Can someone send through a stacktrace ?

bit of a newbie when it comes to debugging
is this what you're after?

[Omer Akram (om26er)]

Thanks for the bug report. Please test against latest unity in natty if you are able to reproduce this problem. I am not able to reproduce this crash with the provided steps.

[Ynot (tatkinson321)]

Can't reproduce the decorator crash
Problem seems solved

[Omer Akram (om26er)]

closing this bug then :) but feel free to report any other bugs you may find.
