When I turn on my linux laptop, I am informed that kdeinit5 has crashed. This appears to have no impact, I can use Firefox normally and the kde plasma widgets and toolbar appear as they usually do. I'm including two sets of crash information from two boots.

Boot 1

I turned on my computer, and was informed twice that kdeinit5 had crashed, and the the Baloo File Indexing Daemon had crashed.

First window

(kdeinit5, pid 6374)

The crash information could not be generated

Second window

(kdeinit 5, pid 6428)

Boot 2

After opening a text editor to record the above information, I restarted my laptop. This time, the Baloo File Indexing Daemon didn't crash.
