Thanks, but I already have that desktop:
$ cat /usr/share/applications/lyx-qt.desktop 
[Desktop Entry]
Encoding=UTF-8
Name=Lyx
Comment=WYSIWYM document processor
Exec=lyx-qt
Icon=lyx-icon.xpm
StartupNotify=false
Terminal=false
Type=Application
Categories=Qt;Application;Office;
MimeType=text/plain;

So, still awaiting a fix...
