Could be anything from bad source footage interpretation to unfavorable compression patterns in the source footage not resulting in a sharp decode to sub-pixel placment (fractional values) to OpenGL and/or a specific plug-in kicking in at this point. Impossible to tell without more info.
Erm... Well it works fine when RAM previewing, What more info would you need?
Well, composition size and frame rate, what kind of sources are involved, what effects... And things working in RAM preview doesn't realyl mean anything. Some effects work differently on teh render queue if e.g. they revert to software only mode instead of using OpenGL or doing temporal analyses that they don't do while working. Similarly, enabling field rendering, motion blur and otehr stuff can have a massive effect on effects that respond to these specific features...

I hope that is enough?

There is something at that spot, that precise frame. It is a source item or precomp.
My workflow never uses AE to do heavy compression or transcoding. I'd be rendering out to a standard codec and then bring that movie back into Adovbe Media Encoder to get the flv output.
Yes, it seems to be a particualr Pre-comp... What do you mean by render to standard codec?
You're rendering to flv, that's not a standard video codec, it's a wrapper, just like AVI or QT. Mostly, FLV is using a highly compressed codec.
Looking at your list of footage items, the mp3 might be causing this glitch since it has to be decompressed on the fly during the render.
Flash Video FLV files usually contain material encoded with codecs following the Sorenson Spark or VP6 video compression formats. The most recent public releases of Flash Player (collaboration between Adobe Systems and MainConcept) also support H.264 video and HE-AACaudio. All of these compression formats are currently restricted by patents.
