Attached are the results from `pacman -Qe`. (Installed packages with versions AFTER removing konsole.)

SUMMARY
I did not install the konsole package as I had planned to use Alacritty for my terminal emulator.
I was able to install Alacritty and run it without issue from the application launcher.
I opened System Settings -> Default Applications and used the drop down for "Terminal emulator" to select Alacritty and noticed no issues. However, when attempting to use the Right Click -> Context menu -> "Open Terminal Here" option inside Dolphin, nothing appeared to happen. 

Steps Taken and Results:
Additionally, Neovim was selected as my Default Application for "Text editor". 
- Attempting to use Right Click -> Context menu -> Open with Neovim from Dolphin would result in an error from the notification menu/journalctl. 
- Attempting to open Neovim from the application launcher would also result in an error from the notification menu/journalctl.
- Opening Alacritty and running nvim command would work as expected.

I installed the konsole package and set it to the Default Application for Terminal Emulator.
- Installed using `pacman -S konsole` 
- Dolphin -> Right Click -> Context Menu -> "Open Terminal Here" would open konsole at the location as expected.
- Dolphin -> Right Click -> Context menu -> "Open with Neovim" opened the file in Neovim inside konsole as expected.
- Application Launcher -> Neovim would open nvim in konsole as expected.

I changed the Default Application for Terminal Emulator back to Alacritty using System Settings drop down in Default Applications:
- Dolphin -> Right Click -> Context Menu -> "Open Terminal Here" would open Alacritty at the location as expected.
- Dolphin -> Right Click -> Context menu -> "Open with Neovim" opened the file with Neovim inside Alacritty as expected.
- Application Launcher -> Neovim would open nvim in Alacritty as expected.

I used `pacman -Rns konsole` to remove the konsole package and config files:
- Dolphin -> Right Click -> Context Menu -> "Open Terminal Here" would open Alacritty at the location as expected.
- Dolphin -> Right Click -> Context menu -> "Open with Neovim" opened the file with Neovim inside Alacritty as expected.
- Application Launcher -> Neovim would open nvim in Alacritty as expected.

STEPS TO REPRODUCE
1. Install `plasma` package group from Arch repo.
2. Install `dolphin` package from Arch repo.
3. Install `alacritty` package from Arch repo. 
4. Install `neovim` package from Arch repo.
5, See SUMMARY section above for additional steps taken.
