Definitely sounds like bug #72545 is could be a duplicate, but I couldn't say for certain. Whenever I suffered this bug, I was definitely working with Konsole as well, though I'm not certain whether I had invoked sudo manually.
I tried reproducing both this bug and bug #72545 per the given instruction right now, but no such "luck", i.e. I couldn't reproduce either of them. Unfortunately, this bug has always appeared to be quite non-deterministic. -- kdesu will not start apps https://launchpad.net/bugs/50971 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
