The application fails to start with the message below

Please let me know if you need more details. Thank you.
The issue has been fixed by removing *.desktop files containing CP1251 characters. The system is configured with LC_ALL="fr_FR.UTF-8". Sorry, I can't provide you with the files since I have deleted them. I suggest to keep the issue opened and investigate how AppFinder works with unusual *.desktop file contents. My point is that AppFinder should not fail if it encounters a file it's not able to handle. User also should be notified (at least in the console) about the broken .desktop file.
This should work fine in the new appfinder.
