dr konqi report with backtrace

SUMMARY

Application: dolphin (20.03.90)

Operating System: openSUSE Tumbleweed
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.69.0
Qt Version: 5.14.1
Kernel Version: 5.6.4-1-default
OS Type: 64-bit
Windowing system: X11

I was running SimpleHTTPServer (python3, inside of pipenv enviroment) in the Konsole pane of Dolphin. Was running for over an hour, then I shut off the server with a keyboard interrupt. I then tried to close the Konsole pane with the 'exit' command in the terminal, this caused Dolphin to crash completely. There were 3 tabs open when this happened.

STEPS TO REPRODUCE
1. Open 3 or more tabs on Dolphin

2. Open Konsole pane and run 'pipenv run python3 -m http.server' (SimpleHttpServer)

3. Make some requests from the server, then shut it down with Ctrl+C keyboard interrupt

4. Type 'exit' into Konsole panel to close panel

OBSERVED RESULT
Dolphin crashes immediately.

ADDITIONAL INFORMATION
I have been able to reproduce the bug but it only occurs if there are at least 3 tabs open on Dolphin and that a certain number of requests are made to the server. I have not yet pinpointed how many requests or if there is a specific amount of them needed to cause a crash.

Attached is a Dr. konqi generated report (original from time of one of the crashes)
