I installed CodeBlocks from terminal with command sudo apt-get install codeblocks on Kubuntu 14.04 and then file manager started lag. I restarted computer and had error "Could not start d-bus. Can you call qdbus?".
I have tried all suggestions in the google. I saw it was a bug. Somebody had solved the problem for example by removing quotes in qdbus="QT_SELECT=qt4 qdbus". I have tried it.I also tried reinstall kde, qt, xorg. But for me nothing had helped.
Any ides what I could try to fix this situation? Could it be this error for installing CodeBlocks?
