After installing kde3.1.1.a from source everything was good for about a week until I chose to open some HTML documents in Kate and told kde to remember the file association. Now konqueror won't open web pages, instead prompting me to open them or save them to disk.
I used the File Associations manager to change the default application for documents of type text/html back to Konqueror. Now I get the following error message when I try to open web pages:
"There appears to be a configuration error. You have associated Konqueror with text/html but it can't handle this file type."
Can't be good...
