[Dmitry Shachnev (mitya57)]

Got this on Classic desktop, with minimal count of plugins, on Intel video (bug 756452)

[Dmitry Shachnev (mitya57)]

Usually I get it every time when I run "compiz --replace", but today everything went correctly. Does anyone still get it? (I mean the last 2-3 days).

[Léa GRIS (lea-gris)]

Crashed here shortly after login using classic Gnome (no unity).

[Ramon Casha (rcasha)]

Over here it crashes every single time I click on the "system menu" on the title bar. Using classic Gnome. I tried several themes but all of them produce the same result
