Opening desktop shortcut to LAN share results in error "Invalid desktop entry"

[Leó Kolbeinsson]

Running Lubuntu Hirsute 21.04

1. Created a shortcut on the desktop with PCManFM-Qt to a File and/or Folder on a LAN share (SAMBA).

2. Next step was to open the file

3. Result was following error "Invalid desktop entry file: 'smb://brennusel.local/sambashare/Gogn/Testing/leo_test.odt'"

4. Also attempted the same with a pdf file = same results Invalid desktop entry file: 'smb://brennusel.local/sambashare/Gogn/Testing/bugs_reports.pdf'"

This maybe linked to bug # 1875717 which was I originally filed against LibreOffice (possibly erroneously?)
