debsums reports everything's fine.  I moved away the config file, and
now it seems to be OK.  Apart from GUI settings the major difference in
the configs are:

Now:

ReverbRoom=0.200000002980232
ChorusNr=3

Before:

ReverbRoom=1.14999997615814
ChorusNr=53

A quick test now showed the problem:  simply put the reverb to the max,
stop qsynth, restart qsynth.  W/o making any sound, it will go into a
distorted feedback loop that will fade away crackling.  I guess that
would be normal, maybe.  That w/o any sound the reverb engine would
'feedback'.  In any case, I do not use such a high reverb level, but it
was set like that as maybe I tried something before.

Thanks.
