Title:
Crash in software-center when starting service com.ubuntu.sso
Status in “software-center” package in Ubuntu:
Incomplete
Bug description:
When I open the ubuntu software center, it just crashes.
I did some ultra basic debugging, and it appears to a be a problem
while starting "com.ubuntu.sso" service.
This happens every time I open USC. As of now, I USC is completely
useless for me..
