Package: libxcb1                         
Version: 1.8-1
Severity: critical
Justification: makes unrelated software on the system break


since libxcb1 upgraded to 1.8-1 alsamixer segfaults on startup.
Downgrading libxcb1 to 1.7-4 fixes this.
The system is a typical workstation with all the GNOME-bloat (and hence
also pulseaudio) installed.
