Crashes when Passwords for Monitoring-Servers change

[froemra]

Nagstamon crashes at next start when Passwords for Monitoring Servers Change and Passwords are not changed in Nagstamon before.

Workaround ATM is not letting Nagstamon connect to Monitoring Servers (pull ethernet). Nagstamon then starts but cannot connect, but doesn`t crash. Then change Passwords in Nagstamon. Then Plugin Ethernet and it works hopefully ...

I faced an issue which may be related. I tried to add an icinga 1.x server to a fresh install, after saving settings with password, nagstamon crashes. Any startup results in crash. After finding this issue i tried without saving the password
which brings me a bit further, but after setting some filters it still crashed and is more or less unusable right now.

I got the following crash output on commandline which may help:
