-- Information about the crash:
- What I was doing when the application crashed:

I was trying to get more info on another Konsole bug (not remembering windows size) and I was changing selected profile for one window, changing remember window size option and "Ctrl + Shift + N" opening new instances. After changing default profile option crash occured.

The crash can be reproduced sometimes.

Comment 1 nsprangers@gmail.com 2021-09-04 19:03:27 UTC 
I can reproduce this on version 21.11.70 (current git) but not on 21.08.0 (packaged with Manjaro).

It reliably crashes when selecting "Default [Read Only]" and clicking "Set as default" with this error:

ASSERT: "_profiles.find(profile) != _profiles.cend()" in file /home/nathan/kde/src/konsole/src/profile/ProfileManager.cpp, line 414

Cannot reproduce on 21.08.0 (Manjaro) version.

Fix crash in ProfileSettings

Fixes the following crash

- Open Settings -> Manage Profiles...
- Click on a non default profile and edit it
- In "Edit Profile Dialog", check "Default" to make this profile default
- Click Ok, Now we are back in "Manage Profiles" dialog.
- See that "Set as Default" is still clickable, clicking it crashes konsole
