the simplest fix is to just inherit xdg.eclass
Database needs updating iff the installed .desktop file has associated mimetypes. qt-creator doesn't have one.
Oh, sorry about it then, didn't notice before. My request is then "add mime type info and update desktop database". Arch Linux uses: ``` MimeType=text/x-c++src;text/x-c++hdr;text/x-xsrc;application/x-designer;application/vnd.nokia.qt.qmakeprofile;application/vnd.nokia.xml.qt.resource; ```
Should be fixed in 4.1.0
