I did some better tests. Quite often the program doesn't really start,
i.e., it is running but no GUI appears. This happens when I run it via
gnome menu.

Later on, I try to run it again, from an xterm, to check what happens.
Until today I never checked if any other qutecom was running. Now I
found that this problem happens when another quotecom is running.

No, when another qutecom is running but "invisible" since no GUI is
shown, this is what happens:
