> Moreover, titles are not updated immediatly. 

A title update occurs about two seconds after user input.  Title updates do not happen unless there is user input to the terminal.  There are several reasons for this:

- Performance: To avoid waking Konsole up continually to poll the terminal state
- Avoid flicker: Prevent the tab title from flickering when running a script or other activity which starts lots of processes to accomplish its task
- Relevance:  When a long-running command finishes, the name of the tab title would go back to "currentdir : bash" or similar, which is less useful than "currentdir : name-of-last-task-you-started"

> Anyway, while the current user on the shell is different from the

Probably a permissions issue.  If for some reason Konsole does not have permission to read information about the foreground process it climbs up the process hierarchy until it finds a process whoose permissions it can read and then uses that.
