This is still an issue with linux 4.5.4 as well.

I'm using a GeForce 7150m and am getting the same error:

May 14 14:16:00 bslxhp64 kernel: nouveau 0000:00:12.0: plasmashell[8397]: fail

As a side note, I've been seeing these errors since updating from plasma4 to
plasma5 (a couple of months now), and thus far have been uncertain whether or
not this is a driver issue or a plasma issue.
