Version: (using Devel) Installed from: Compiled sources OS: Linux Steps to reproduce: 1. In the Add Widget dialog, add two identical plasmoids. 2. click on the "minus" symbol this will remove all plasmoids of the same kind in all containments and all activities. It happens with all plasmoids i have tested.
