Crashes in Plasma FrameSvg, re-assigning

Comment 2 Nate Graham 2020-01-31 19:50:41 UTC

Is this still happening for you in the latest version?

Comment 3 Carsten Clever 2020-01-31 20:54:25 UTC

Haven't seen this since quite a while, maybe since I switched to openSuSE 15.1.

Comment 4 Nate Graham 2020-01-31 21:21:30 UTC

Thanks!
