When loading a project file (which contains a WDataSetScalar and a WDataSetDTI) OpenWalnut often starts an "infinite" loop (Of course, I guess the error output is not really repeated infinitely, but maybe printed for every voxel of the data set). On Average, this happens in every third start of OpenWalnut. (System: Ubuntu 12.04 64bit, GeForce 9800 GT/PCIe/SSE2, AMD Phenom(tm) II X4 920 Processor × 4 )

Some details: -the error does NOT occur when loading one data set manually -the error does NOT occur when loading a project file containing one data set -it seems that there is only an error when there are two different types of data set together in one project file (but no error when e.g. loading two DTI data sets) -OpenWalnut seems to work fine in the background (it loads all the modules and data sets), but very slowly and therefore unusable

The debug output starts with:

...

...and then there is a loop of:

    depth=CullVisitor::apply(Geode&) detected NaN,
    depth=CullVisitor::apply(Geode&) detected NaN,
    matrix={
