qvm-run qubes.StartApp+ not handling long names of .desktop files

[Szewcson]

How to file a helpful issue

Qubes OS release

4.1

Brief summary

"Installed" Telegram AppImage that creates own .desktop shortcut. When I want to run it from qubes "start menu" nothing happens. After small investigation I found out that if I create .desktop file with long name it is visible in the menu but it not work (also from the CLI), but same file with short name works as normal. Original nameame of that Telegram app shortcut is appimagekit_e9d4f8123d28a5a3f93f92ec58a23421-Telegram_Desktop.desktop

Steps to reproduce

1.) Create .desktop file in ~/.local/share/applications with long name (use the one from Telegram app to be sure is long enough) 2.) Refresh Applications 3.) Try to run application from the menu, or using qvm-run with qubes.StartApp+

Expected behavior

Application should run as normal

Actual behavior

Nothing happens
