Bug description

I am there on Manjaro Linux with Cinnamon DE, and the issue is 100% reproducible. When trying to activate a WLAN Hotspot (AP) with the NetworkManager GUI, Cinnamon-Settings crashes.

Steps to reproduce

From the task bar, open the NM menu
Click on "Network settings". A window opens up.
To start AP, click on the button "Use as wireless access point"
The AP is starting
Stop AP by turning it off from the same window or switch to another network.
Repeat the steps to start AP
Expected: The AP should come up again. Actual: Window closes immediately, and in Systemd journal, an segfault is output.

If, however, I delete the Hotspot configuration in between, it is working as expected. I delete it like this:

From the task bar, open th NM menu and click on "Network connections"
Choose "Hotspot", and click on the button with the minus symbol to delete it.

Expected behavior

Start the AP just as before.

Additional information

This is especially annoying because it is not possible to set a user-defined WPAx-Key with this bug, since the connection has to be deleted as workaround.

This is the beginning of the Systemd journal:

I need a CoreDump or a better stack trace for this
