I'm not a valgrind guru, so I didn't know about that. Here is the new result
(as you seen not all of the kdelibs is compiled with debug info,
but it should be traceable). Looks like the KFind object is already deleted when
the KHTMLView is destroyed. Hm, d->m_find is created with:
d->m_find = new KFind( d->m_findDialog->pattern(), 0 /*options*/, widget(), d->m_findDialog );
Is widget() here a KHTMLView? If so, it's clear why we don't need the delete in the
KHTMLPart dtor.
