I started multiple applications with the shortcut alt+space, the applications were discord, kile, dolphin and firefox, when I opened firefox krunner crashed. 

- Unusual behavior I noticed:

Playing music with the vlc media player lagged as well as playing music on youtube in firefox. 
there was a huge cpu usage from changing programms

*** This bug has been marked as a duplicate of bug 363136 ***
Comment 2 Christoph Feck 2018-01-10 18:24:56 UTC 
Only correcting this duplicate, because it seems to be a common recent regression with sqlite3.
