Yesterday I encountered a problem on both of my two laptops (both using Ubuntu, one is 20.04.5, one is 22.04).
The problem was a crash popup "The application Passwords and Keys has closed unexpectedly". One had a crash around the time I came home and opened it (it was running the whole day). The second one got the error about an hour later, about 4 minutes after I powered it on.
After I checked the crash logs of seahorse, I found following on both of them (times differ):

then I checked the syslog and found this for avahi:

What could have caused this to happen on both laptops? Should I be concerned? I am new to mDNS. Both laptops are on the same network, together with 2 smart devices.I didn't configure avahi on any of them and I barely use the first laptop. Thanks
