On some websites (I unfortunately do not know of any others, nor do I know what causes this), lines of HTML code are not selectable while using arrow keys.  
I have not, unfortunately, been able to reproduce this at will, though this is the second time it's occurred (different sites each time), across different WebKit versions (I do not remember the first occurrence's version, but believe it to have been a nightly from within 2 weeks of today).

Though it is not shown, those lines where the selection bar does not appear behave the same way when clicking the actual line.  It's apparently selected (via the right column details and the breadcrumbs on the bottom), but is not highlighted.

Notes:
I am running SIMBL 0.9.6c with SafariStand 4.0SL169, both of which (as I understand) are in somewhat-beta status, and SIMBL still relies on code injection.  
The previous error occurred on OSX 10.5, with earlier versions of both (though I do not recall which versions, and installed over the top, so the information is unretrievable).

I was able to find the web page your movie seems to be showing here:

I was unable to reproduce your problem, though I guess that's not unexpected given that you say it's intermittent.

You appear to be executing a set of focus changes, mouse moves, mouse clicks, and then keyboard presses, which you can pretty much figure out from watching the movie.  Any feelings on whether any of these might be significant parts of recreating the problem?

Seems a little odd in your movie that when inspector gets focus, that the "line over the mouse" isn't the one "highlighted" - the line elements down is.  Specifically, the mouse appears to be over

   <p style="text-indent:-83.2px;font:12px Verdana;margin:0 0 0 83.2px;">

but 

   <strong>set</strong>

appears to be "mouse highlighted".

Note that your use of SIMBL plugins is of course completely unsupported (AFAIK) - see the first entry in the WebKit FAQ: 

   http://trac.webkit.org/wiki/FAQ

Though my understanding is that SIMBL plugins aren't even usable, as in won't be loaded, in 10.6 if you run in 64-bit.
