I have all my symbols size set using Map units. It looks great in almost all zoom levels but at one zoom level the houses (one of the layers) becomes incredible large!

Is the symbol used part of the qgis library? or is a custom one? If is the latter can you attach it? what are map units in your project?

I may have understand the issue. What scale and how many map units are you using?

From 1:74000 and up (more zoomed out) this behaviour appears. And for some reason it's only one of all symbols that gets this crazy size. And the other symbols come from same font. The size of the symbol is 25 map units (i e 25 meters). For your knowledge, the symbol size changes also radically in the preview in the layer list.

and what would be this specific symbol?

What I see is a slightly different issue, but maybe related (and I'm seeing it in qgis 1.8 up to master):

for font marker symbols, when defined in map units, then they all render as expected only starting from a certain scale. Before that they render the same size (so wrong) and a message shows in the log:

QFont::setPixelSize: Pixel size <= 0 (0)
