Comment 5 for bug 1492437

I did a fresh install because this was a bit old and upgrading since Utopic could cause various problems.

The problem still exists. Also, apport has created a crash report, when unity crashed. I did

$ ubuntu-bug /var/crash/_usr_bin_compiz.1000.crash

but I'm not sure if the report uploaded correctly (both .upload and .uploaded files are empty).

If you want the crash report here I can attach it, just let me know.
