Hi Mario,

I've just done some testing on a single screen here and get a crash as
well after interacting with the scene for around 30 to 60 seconds.
I've just force single threading via the OSG_THREADING=SingleThreaded
env var setting and so for it's not crashing.

My guess is that this crash is unrelated to Mathias changes and is a
general threading issue, but... one can't rule anything out at this
stage.

Robert.
