I had my first ever camera housing leak this weekend. I noticed on our second dive that the port on my MDX-D300 was fogged up. Then I noticed fogging on the viewer window and the settings window as well. I wrongly assumed that I had left the camera in the sun too long, although it was in my insulated bag on the boat while we ate lunch.
When I took the camera out of the housing at the end of the dive, there were droplets pretty much throughout the housing, in all corners. Uh oh. I couldn't find any sign of contamination on the o-rings, so I waited to rinse and inspect when we got home. I dried everything out (fortunately, no apparent damage to camera or lens) and put the housing in the sink for about an hour. After drying, I opened it to find a tiny trickle behind the "OK" button on the lower back. This is the bottom button and the most vulnerable, and had been damaged by the previous owner. I suspect she dropped the housing once, but I've never had trouble with it before. I checked the button and found it wobbly, then turned gently and found that it was less than finger tight. I was able to easily unscrew the base from the housing.
This could have been disastrous. I was very lucky.
Word to the wise, check your buttons and levers inside and out periodically. Look for any looseness or wobbles.
