since some days my Files lens opens only nautilus but not the correct application which is associated with the file extension. For example, if I choose a PDF file, Nautilus is openend, pointing to the directory there the file is (and the file is selected) but Adobe Reader is not opened.
Then I do the same in the terminal with
only Nautilus is opened too.
xdg-mime shows me this info:
$ xdg-mime query default application/pdf acroread.desktop
The /usr/share/applications/acroread.desktop file:
[Desktop Entry] Name=Adobe Reader 9 MimeType=application/pdf;application/vnd.fdf;application/vnd.adobe.pdx;application/vnd.adobe.xdp+xml;application/vnd.adobe.xfdf; Exec=acroread Type=Application GenericName=PDF Viewer Terminal=false Icon=AdobeReader9 Caption=PDF Viewer X-KDE-StartupNotify=false Categories=Application;Office;Viewer;X-Red-Hat-Base; InitialPreference=9
The same with other file types like images, music files and office documents.
Then I doubleclick the file in Nautilus everything is ok and the correct applications are opened.
I assume this behaviour has something to do with Thunar which I've installed some days ago but deinstalled after these problems.
