For the longest time I could not figure out why everytime I launced Konqueror 
it defaulted to khtml part when I had chosen webkit part to be my default html 
handler. I finally discovered that this happened because I have had saved the 
webbrowsing profile and it contained the servicename parameter which was set to 
"khtml". The unfortunate side effect of that is it completely overrides the 
user's own preference set in filetypes.

As such should not Konqueror at least check to see if the current handler for 
the specified "servicetype", e.g. text/html, is still the same as the one saved 
in the profile file and if not simply default to using the one currently set 
instead of blindly following what was added in the profile ? I was originally 
going to suggest that this information should not even be read by Konqueror, 
but looking at the code in KonqViewManager::loadItem (konqviewmanager.cpp) it 
seems that idea will probably cause other problems when Konqueror's start page 
is set to "Show Introduction Page" ??
