Description Synthetic451 2018-03-09 05:23:15 UTC 
Just updated to Plasma 5.12.3 and KDE Frameworks 5.44 in Fedora 27. When using the icons-only task manager, I see a bunch of error messages in syslog when mousing over the application icons.

Steps to reproduce:

1. Switch to Icons-only Task Manager
2. Pin a few applications onto the task manager and open some windows
3. Mouse over all the icons and see messages spew in syslog

I have same problem at Plasma 5.12.6 and KDE Frameworks 5.47.0 on Ubuntu 18.04, when using default task manager (not icons only) and hovering on pinned apps icons, after some days my .xsession-errors have size more than 1 gigabyte with records like:
```

This is fixed in Plasma 5.13. We might look into backporting to 5.12.
Comment 4 Serhiy Zahoriya 2019-02-10 00:37:00 UTC 
Maybe it wasn't completely fixed. Getting the first error on 5.14.90. Will continue in https://bugs.kde.org/show_bug.cgi?id=396316
