I had this with 4.6.2 as well -- but *NOT* with earlier 4.6 versions -- it 
was new to 4.6.2.

Do you use a proxy?  That seemed to be the issue here.  Earlier kde4/
konqueror (4.2/4.3 era) had rather widespread proxy issues, but they 
disappeared with newer versions, at least here, until 4.6.2.  Ultimately I 
believe both kde/konqueror and my proxy (privoxy) updated, so I don't know 
for sure which fixed the problem earlier, just that it eventually went 

But I made a single tweak with 4.6.2 and solved that issue here.  AFAIK 
the issue is related to a HTTP 1.1 persistent connections mismatch between 
konqueror and the proxy, so if they're both set the same, it should work, 
otherwise there might be problems.  In any event, the single tweak I made 
was to konqueror's proxy settings.  Previously, "Use persistent 
connections to proxy" was unchecked.  Now it's checked, and I've had no 
further problems.  But depending on your proxy, you might have the reverse 
issue and have to /uncheck/ it.

Whichever way it ends up working, hopefully toggling that works as well 
for you as it did for me. =:^)

The following is very much my own opinion and observations.  It's very 
much NOT an official kde stance, which I couldn't give anyway as I'm not a 
kde dev.

Yes and no.  The old khtml engine isn't under as heavy development as it 
once was, but it formed the basis for webkit, which in turn is used by 
rekonq, a kde-based experimental browser.  Apparently with rekonq 
installed (I say apparently because I don't have it installed here so this 
is based on what I've read) it's now possible to switch between the khtml 
and webkit rendering engines for konqueror as well.

Given the larger market share and development resources webkit has, with 
support from both Apple (safari?) and Google (chrome/chromium) among 
others, and the fact that qt has native webkit support as well, many 
people are observing that it's probably unrealistic for kde to continue 
development of khtml in the longer term, and predicting a switch.  
However, with konqueror now able to use either the khtml or webkit kparts, 
it's unlikely that konqueror itself will fade.
