subtreespecification editor and writing a subtreespecification with an LDAP
filter the SubtreeSpecificationParser *sometimes* gets killed.

subtreespecifications w/o an LDAP filter the parser seems to be stable. But
when adding it just after starting the server the parser dies with an "Read
end dead".
