Strange message banner during dnf update

[jd1008]

Got a banner pop-up saying

Application: kded5 (deleted) (kded5 (deleted)), signal: Aborted
[Current thread is 1 (LWP 2422)]

Thread 1 (LWP 2422):
#0  0x620c8a5d in ?? ()
Backtrace stopped: Cannot access memory at address 0xb877c250
================================================


The process is still running though:

$ ps -p 2422
   PID TTY          TIME CMD
  2422 ?        00:00:04 kded5

Not sure what to make of it.
