segfault: multiple windows close crashes program #189
Description
I encountered a segfault during messing around with multiple windows.
The most stable way I found to reproduce it is:
- run Verso
- press new window button
- after new window spawned, press it again on the first window. wait for the 3rd window.
- close one of the last two windows with system close (not from verso-panel)
It seems it's something with wayland. (my system is an Ubuntu fork, wayland, plasma 6)
