You are hijacking this thread because the problem of the OP doesn’t seem to be the one that you solved removing that package. We can be wrong, but there were slightly different symptons that can point to a different direction.

There are some rules in this forum (and usually in whatever forum you participate). So don’t complain if you break some rule and someone warn you about that.
