Zip the full log and post it, please. I'll decide myself what is meaningful or not in it, if you don't mind...
There's however a novelty about this bug: if it exists in the Cool VL Viewer, it shall now exist too in LL's release viewer, because they adopted that code in it recently. I'll disable the "gimbal lock fix" code for the next releases of the Cool VL Viewer, but it'd be nice if you could reproduce the bug with LL's viewer (I know, running LL's viewer is not really appealing...) and open a JIRA for it, so that they (and especially the code author) can have a look at it and fix it.
