I'm trying to package scidavis http://scidavis.sourceforge.net/ and i would like the files generated by it (*.sciprj and *.sciprj.gz) will be associated to scidavis and opened in it when i double-click on their. So i put a desktop file in /usr/share/applications : [Desktop Entry] Encoding=UTF-8 Name=SciDAVis Comment=Scientific Data Analysis and Visualization Comment[de]=Visualisierungs- und Datenanalyseprogramm Comment[fr]=Outil d'analyse scientifique de données Icon=scidavis Exec=scidavis %f Terminal=0 Type=Application Categories=Science;Graphics;X-Fedora; MimeType=application/x-scidavis X-Desktop-File-Install-Version=0.13 and a xml file in /usr/share/mime/packages : <?xml version="1.0" encoding="UTF-8"?> <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"> <mime-type type="application/x-scidavis"> <comment>Scidavis project</comment> <glob pattern="*.sciprj"/> </mime-type> <mime-type type="application/x-scidavis"> <comment>Scidavis project</comment> <glob pattern="*.sciprj.gz"/> </mime-type> </mime-info> after this i run update-mime-database /usr/share/mime update-desktop-database but the problem is that when i create a sciprj file using scidavis the mime-type associated in nautilus is text/html Someone could help me to clarify this ?
