Description of Problem: Performed an installation of beta4, choosing KDE, but not gnome. Within konsole, if you hold the "New" button, you get options for "Midnight Commander" and "Root Midnight Commander". Using either of those options launches a new konsole that immediately exits. Odds are it's trying to run a binary that's not installed. Either there should be a dependancy on mc for konsole, or those tabs should not show up unless mc is installed.
Did you install midnight commander?
No, no mc RPMs on the system.
Dependency is far too heavy for this. However, an more verbose error could be printed than "session midnight commander ended with error code 127" which is what is printed now... Will forward upstream as a wishlist.
This will be fixed in a future Fedora release if upstream provides a solution. The issue is recorded here: http://bugs.kde.org/show_bug.cgi?id=120322 Please direct your further comments or remarks to this KDE Bugzilla entry, thanks.
The problem will be fixed in the upcoming Fedora Core 5, that is, the session types that are not available (their executables are missing) are not shown in the menus.
