Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.16.16-arch1-1 x86_64
Windowing System: X11
Distribution: EndeavourOS
DrKonqi: 5.24.3 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I just typed the following: someList<-vector("numeric") and then it crashes in a similar fashion to when it did when I reported the same bug when creating empty lists.

The crash can be reproduced every time.

-- Backtrace:
Application: Cantor (cantor), signal: Segmentation fault
