[SOLVED] NetworkManager core dumped

Since the last system update (2 days ago) I noticed that NetworkManager is crashing now around twice per day.
After the crash, the NM system try widget (I am on KDE) also doesn't show me any connections anymore although I am still connected via ethernet + OpenVPN.

coredump info:

Any ideas on how to troubleshoot this?
I already disabled my dispatcher script (by renaming it to .bak at the end).

Re: [SOLVED] NetworkManager core dumped

From the backtraces, 79655, 79658 and this thread are all the same.
And for fairness sake: glib2 was updated to glib2 2.78.0-2 on 2023-09-12 07:58 UTC - 4 minutes *after* Utini encountered the crash and 16 minutes before his post.

Re: [SOLVED] NetworkManager core dumped

Yep the glib2 update seemed to have helped.

I had the crashes yesterday and today.
Both times my pacman -Syu was up to date ;-)
