Could it be that this behavior was "introduced" by the "loseless" software
section filtering some month ago?

Andreas Oberritter had some weeks ago already ask if the section filering
could be reverted to the old code, because the new code isenīt as loseless
as the old code.

BTW: Since some month i have sometimes kernel traps with symbols from
demux/filtering stuff.
