Update screen is blank

[bonnevie]

I've been getting a blank "update screen" for the last few days when I use "Install updates".  When I update through the command line, I do see stuff to be updated.  The install function is doing its job, the only problem is that whatever needs to be updated won't show up in GUI mode.(at the end of the process, the update window does show me what's been updated).  I only see this in the machine described in the left profile.  No problem in VM 3.4 or in Lenovo LL 2.8
