#118 pyFoamPVSnapshot.py (and other) utilities crash under OpenSuse 12.1 (python 2.7)

Hi Bernhard!

we already talked about that. I have not been able to get the Snapshot utility running.

Starting pyFoamPVSnapshot.py gives me Output 1 (see below). The same happens for several other utilities which need gzip.py. In http://docs.python.org/dev/whatsnew/2.7.html I found that there was a change in Python 2.7.

If I comment out FileBasis.py:9 I get Output 2 which is more related to the paraview stuff.

The LoadState-utility is running well but none of the paraview-examples is runnging.

The version information you find under Output 3.

Regards, Markus.

Hi Bernhard,

I noticed that the gzip.py-issue was only due to a wrong path was added to PYTHONPATH. So the relevant error message is output 2.

OK. I'll have a look. First make sure that the utility works on all my available systems (with PV 3.12 ... BTW: this happened with older versions too I suppose). If it does I'll try to pinpoint the system

@pythonpath: I found that on some systems the precompiled PV brings its own python-interpreter with its own libraries and this might mess up the standard-python if the PYTHONPATH is set unwisely
