Description mombelli.mauro 2014-04-28 21:28:54 UTC

alt+f2, do some basic math (division, multiplication, "enter" to work with result) and if i leave the bar opened for more than10-15sec it hungs the system, or i kill it by virtual console or the system will kill it for me.

High reproducibility, it will also hung X. tell me what to do/debug and i'll do it.

ps. it hung ram 78% of 8GB and multiple core of cpu, it was over 200% CPU in "top" (and my system is a tricore.. the rest was xorg)

Reproducible: Always

Steps to Reproduce:
1. do some math
2. leave the gui open
3. crash!
Actual Results:  
x hungs for some sendons, the systemd (i think) kicks in and kill krunner

Expected Results:  
just sit there showinge the result.

delve . -a -1 | grep '^2' | wc -l return 0
and
baloosearch '=2*2'
is fine for me

Comment 4 Christoph Feck 2014-04-28 22:51:25 UTC

If this is reproducible, please disable krunner plugins to find out which one is the culprit. For example, if you think the calculator plugin causes the issue, try enabling only that plugin, or try disabling it.

To disable plugins, click on the Configure wrench in the Alt+F2 dialog.

Comment 5 mombelli.mauro 2014-04-28 23:01:49 UTC

Thanks, from "the wrench" i found out search plugin was still enabled (i had "disabled" it removing the .desktop in /usr/share/kde4/services/plasma-runner-services.desktop). 
disabling it from there has fixed the hung!

so this is now 332253 duplicate
