Details

Description:
On my system krunner eats a lot of memory, eventually not releasing it and leading the system to instability. I can trigger this behavior by opening the launcher window in KDE by pressing Alt+F2 and writing a very simple math calculation, like "360/2=" or "180/3=" a few times. My memory monitoring plasmoid then shows a sharp peak and krunner results in using around 2GB of memory. OOM thread kill log from journalctl is attached.

Additional info:
* package version(s)
kdebase-workspace 4.11.9-2
kdelibs 4.13.0-1

* config and/or log files etc.
Log from journalctl of krunner OOM kill.

Steps to reproduce:
1) open launcher window with Alt+F2
2) type some simple math operations like "45*2=" or "36/3=" a few times
3) keep an eye on memory occupancy

Confirmed. I made about 6 or 7 calculations and the laptop froze. I had to switch to a different tty with a lot of patience and kill the X server which also took me a while :D. I think this should be reported upstream.

Please report this upstream.

Sorry for reporting it also here.

You did it right: reporting it here too made this patch to be applied to baloo 4.13.0-2
