I had the same problems after a recent upgrade from Dapper 6.06LTS to Edgy 6.10. It particularly affected HTML and XML files which I noticed first in yelp - it opened these files in gedit. I also had similar problems with icons like bug 41772. With .tar.gz archives I also got the message "No application suitable for automatic installation is available for handling this kind of file".
The steps below fixed all these problems for me:- It did not seem to be necessary to move or rename ~/.local/share/applications/mimeinfo.cache as reported by jefight for 7.04. I did actually do that first, but when I restored it again after step 3 below, the problems remain fixed. 1. sudo update-mime-database /usr/share/mime 2. sudo dpkg-reconfigure shared-mime-info 3. $ killall gnome-panel $ killall nautilus Haz -- nautilus's clever anti-hax0r detection is really dumb https://bugs.launchpad.net/bugs/19101 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a direct subscriber. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
