screen shot of file manager window that pops up

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
After taking a screen shot, if you click on the option to open the file in its destination folder, Dolphin isn't what's used. It appears that the system uses GNOME's file system utility (not sure if that's the right term). It doesn't hinder usage in any way, just unexpected/quirky/inconsistent. I'm not sure if Plasma 6 addresses it.

STEPS TO REPRODUCE
1. take screen shot
2. click the option to open the containing folder
3. take a look at the window that pops up, as well as its icon in the Task Manager
