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.
