compiz crashed with SIGSEGV in g_closure_invoke()

[wgroiss]

I use Ubuntu 14.10 (Beta) since about 6 weeks. Almost without problems. Compiz-bug appeared immediately after boot and login (no action after login). The only difference to the last login (where no bug appeared) is, that i have new installed "btsync" and for testing i created a test-folder and a test-file on desktop.
