Description René Paw Christensen 2024-02-22 22:52:56 UTC 
SUMMARY
Dolphin tries to process ".desktop" file, even when it is not a text file, and when it is big.
This results in a unresponsive window.
The solution is to set a size limit, on how big ".desktop" files Dolphin should process.

STEPS TO REPRODUCE
1. Create a folder and copy a big file to it (150 MB)
2. Rename the file to ".desktop" or ".Desktop" extension
3. Browse the folder in Dolphin

OBSERVED RESULT
The window does not respond, the CPU goes high.
I expect that Dolphin tries to process the big file, because it thinks it is a text ".desktop" file.

EXPECTED RESULT
Dolphin ignorees (do not process) big ".desktop" files, perhaps > 1 MB.
