After the gcc c++ upgrade I had the same problem as themetman in the thread
xfce4 Desktop launchers no longer work
Desktop launchers and "Open With Other Application..." show error
Failed to run ...
Process ... exited with status 1Panel launchers work fine.
After verifying another account works fine, I found the folder by moving everything out of ~ and moving it back in pieces until I identified the folder causing the trouble.
The solution was to
rm -rf ~/.cacheWith a name like cache I don't expect to be losing anything. My taskbar and xfce settings look to be unchanged.
