OK, I have got to the bottom of this, at least for me. File associations, I finally discovered, are stored in ~/.kde/share/config/profilerc. Somehow, that file had become owned by 'root'. I do not know how that occurred -- I do not remember doing anything that might have caused this e.g. running Konqueror as root, and then changing file associations. I don't know if I have *ever* run konqueror as root -- I'm a shell person. But anyway...
The work around is to do this in a terminal: sudo chown yourusername ~/.kde/share/config/profilerc (replacing 'yourusername' with your actual login name). After this, file associations work fine. Regarding Dolphin. I also had to change my 'Win+Home' shortcut to use Konqueror (I cannot remember if I had changed this to be Dolphin myself or if it was changed for me) - do this under "System Settings --> Keyboard and mouse --> Keyboard Shortcuts", and in the "Command Shortcuts" tab change the shortcut from 'Dolphin' to 'Home folder', which was under 'Lost & found" for me. There is still definitely a bug here, even if it was my own error that caused that file ownership to change -- when file associations are saved to the profilerc file, there should be an error message if the file could not be written to. -- [gutsy] Cannot change default file manager from Dolphin https://bugs.launchpad.net/bugs/157166 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
