If all your input is from this forum, it biases the sampling away from a true random sample. However, the product pool that produced the samples is probably spread out over the production run.
As you say, there is confidence that Leica will successfuly address the problems.
A better way to present this data would be in a simple bar graph or pareto chart. Gives a good visual look at the analysis

I have a feeling 10% is on the high side. Owners with problems are far more likely to report them than owners without problems. One might even argue that camera failure can be a reason to join up on this forum.
Having said that, I have been able to provoke lock-up-reboot on my camera by leaving it in the "press the release button"screen when cleaning the sensor for too long a time. I found this out when my wife *insisted* that I carry the washing basket out whilst I was starting a sensor clean.
