Just in case this is of any help, following is the output of Valgrinds memchecker. \
The sequence of events the messages correspond to are: 1. Start Konqueror under \
Valgrind. 2. Pasting the address \
(http://www.home.unix-ag.org/simon/penguin/penguin.svg)  into the address bar.
3. Pressing enter.
 (waiting)
4. Pressing "Back" button in Konquerors Main Toolbar.
 (waiting)
5. Dr.Konqi shows up -> Pressing close.
