notify-send hangs

Fri Mar 01, 2019 12:53 pm
Hello everyone,
here's my issue.
After a reboot, notify-send test takes a minute or so to give back control of the terminal. I found out about this issue while trying to figure out why some applications in my PC were freezing or hanging.
I have disabled the notifications in Notification Settings -> untick Show application and system notifications. If I tick it, the notification is shown promptly and correctly.
I found out that removing .config/plasma* (or rather, moving those files elsewhere), rebooting, disabling notifications, and rebooting again, solves the issue. Obviously, this is annoying because I lose a lot of Plasma settings. Nonetheless, the fix is only temporary: after some use of PC the issue reappears. However, I can't seem to identify the cause of the issue.

System information:
Recently installed Kubuntu 18.04.2 64-bit
KDE Plasma v5.12.7
KDE Frameworks v5.44.0
Qt v5.9.5
Kernel version: 4.18.0-15-generic
4×Intel Core i3-6100 CPU @ 3.70GHz
7.6 GiB RAM

Here are the .config/plasma* files:
