Somehow this happened on my setup... dont know how. For example in konqueror typing http://www.google.com in is fine -- but clicking for example the 'images' link opens a download dialog with 'Type html' + "what would you like to do with this file". This results from a file being created in ~/kde/share/mimelnk/text called html.desktop containing the following: [Desktop Entry] X-KDE-AutoEmbed=false I'm not sure but this may have been done by Tunderbird maybe -- anyway, there was no way to reverse the behaviour from the KDE control panels. Resolved by removing the file. Reproducible: Always Steps to Reproduce: 1. 2. 3.
And what do you think shall we do when you (or the program you are using) change your configuration?
