initialized value.

[Olivier Goffart]

Hi, 
While running Kopete under valgrind, i got that message:

==16835==
==16835== Conditional jump or move depends on uninitialised value(s)
==16835==    at 0x1BC53693: KHTMLPart::clear() (khtml_part.cpp:1180)

It seems to me that   d->m_bCleared   is not initialised.

I imagine it shouldn't be difficult to fix that. 
I send you a possible patch which fix it. I decided to initialize the value to 
false. But i absolutely don't know if it is the correct choice.

(the patch is against the KDE_3_3_BRANCH)

Should i commit that to head ? and on the branch ?  or let you handle the 
problem ?
