Hi, I don't know how the /usr/share/applications/mimeinfo.cache is built.
But I don't like some ``priorities'' in there, e.g. I'd like to change the sequence of applications for html. Currently I have text/html=seamonkey.desktop;opera- browser.desktop;firefox.desktop;bluefish.desktop;midori.desktop;epiphany kfmclient_html.desktop;kde4-kimagemapeditor.desktop; and I'd like to see midori.desktop first in that list. Editing mimeinfo.cache only helps for a short since it gets rebuilt by nearly? each emerge. Many thanks for a hint, Helmut.
