SUMMARY
While I was trying to connect to my WLAN I was notified of a Baloo Indexer crash. I had also recently had a Suse/Linux software update and not restarted, but I am not sure how to find out what it affected.

I did not try to recreate the situation to see if it happened again.

I am entering this by hand on bugs.kde.org because the KDE crash reporting assistant kept the login button grey although I filled in Username and Password and saw no error in my details and no error message explaining what else was needed.

STEPS TO REPRODUCE
1. 
2. 
3.
