Version: (using KDE KDE 3.5.6) Installed from: Ubuntu Packages In ~/.xsession-errors konsole: WARNING: Unable to use /usr/share/apps/konsole/mc.desktop konsole: WARNING: Unable to use /usr/share/apps/konsole/sumc.desktop This is fixed by installing mc (midnight commander). But I lost some time figuring this out, trying to sort out a different problem. It would be better for the application to warn the user when they try to use some midnight commander functionality, rather than in this log file.
