Description David Nemeskey 2025-10-10 09:07:59 UTC 
SUMMARY
If the name of a directory ends in a space, Dolphin cannot open any of the files in it. It can go to the directory, copy or delete files, create new ones, etc. However, if I try to open one of the files, the icon of the associated application starts bouncing, but then nothing happens.

STEPS TO REPRODUCE
1. Create a new directory with a name that ends in a space (note: Dolphin removes the space automatically, so you have to then rename the directory and add it back. Or create the directory from the terminal.)
2. Copy a file to the directory or create a text file in it.
3. Try to open it by (double) clicking on it or by selecting it and pressing Enter.

OBSERVED RESULT
The icon of the associated application bounces for a while, but nothing happens.

EXPECTED RESULT
The associated application should open with the contents of the file loaded in it.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon User Edition (24.04)
KDE Plasma Version: 6.4.5
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2

ADDITIONAL INFORMATION
If the space is deleted from the name of the directory, everything works again.
Comment 1 David Nemeskey 2025-10-10 09:14:48 UTC 
I have reproduced the issue on another machine:

Operating System: KDE neon 6.3
KDE Plasma Version: 6.3.2
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Kernel Version: 6.11.0-17-generic (64-bit)

I have modified the Dolphin version accordingly to 24.12.2; mine is 25.08.1.
Comment 2 Patrick Silva 2025-10-10 15:23:12 UTC 
Cannot reproduce with Dolphin 25.08.2 on Arch Linux.

Operating System: Arch Linux 
KDE Plasma Version: 6.4.91
KDE Frameworks Version: 6.18.0
Qt Version: 6.10.0
Graphics Platform: Wayland
Comment 3 TraceyC 2025-10-10 21:53:31 UTC 
I can reproduce this with Dolphin 25.08.1 on KDE Neon User edition

I'm not able to reproduce this in Dolphin built from git-master. Double clicking a text file in a folder named "space " brings up Kate, which loads the file. It looks like this is fixed in 25.08.2 and later.
