           Summary: Slow and high CPU when folder contain big ".desktop"
                    file(s)

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.
