Open sigrok. start a new session, fx2lafw. Click on a channel label (on the left side of the main window), e.g. "DO". The window to change its parameters will open with the name already selected. Press backspace to delete the name. Pulseview immediately crashes, printing: "Caught exception of type N6sigrok5ErrorE (invalid argument)" The same happens if you click in the name field and backspace one character at a time, once you delete all characters so that the field is empty, it crashes. Renaming a channel is possible without deleting its name, just start typing the new name instead of pressing backspace, so it's not that critical, I just have to remember to not press backspace or I'll lose the session.
