--- Comment #2 from Lars Winterfeld <lars.winterf...@tu-ilmenau.de> --- When I run kdevelop from the command line without any arguments, a new window opened. But: Thanks for the hint regarding the interprocess communication. It turns out the problem occurs only in a VNC session, but not out of it! So, kdevelop may be innocent. I have an env var DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus Which seems ok? Any hint on which direction to look at to debug this would be highly appreciated. -- You are receiving this mail because: You are watching all bug changes.
