SUMMARY

Dolphin (or is it xdg-open?) has a regression where it no longer launches programs when directly executing a .desktop file. 

This is notably visible when a privacy-minded user downloads and runs the Tor Browser via its "start-tor-browser.desktop" icon.


STEPS TO REPRODUCE

1. Go to https://www.torproject.org/download/ and download the Tor Browser for Linux.
2. Extract the .tar.xz file to your Downloads folder
3. In Dolphin, open the Downloads folder, then enter the "tor-browser_??-??" folder.
4. Click-to-run the "start-tor-browser.desktop" file.

5. Alternatively, from the command line, type:

   $ xdg-open start-tor-browser.desktop


OBSERVED RESULT

The "start-tor-browser.desktop" file opens in the default text editor. This will confuse a new KDE user, and annoy experienced KDE users.

This file has its "Is executable" permission set so this shouldn't be an issue. 

The xdg-open command has the same effect, so maybe the underlying issue is with xdg instead?


EXPECTED RESULT

"start-tor-browser.desktop" should execute its "Exec" line to configure and run the Tor browser.

ADDITIONAL INFORMATION

Since KDE has an explicit goal of user privacy, this bug should be a high priority.
