Bug#754310: netgen: meshing a STEP file makes X crash

[Francesco Poli (wintermute)]

Package: netgen
Version: 4.9.13.dfsg-8+b1
Severity: grave
Justification: renders package unusable

Hello,
I cannot generate a mesh on a geometry described in a STEP file without
experiencing X crashes that force me to reboot the machine.

I can reproduce the issue as follows:

 • take a STEP file, for instance

   $ zcat /usr/share/doc/netgen-doc/examples/frame.step.gz > frame.step
 
 • start NETGEN

   $ netgen frame.step

 • click on "Generate Mesh"

 • minimize the window and then maximize it again

At that point, X crashes and I lose my session. The keyboard is
unresponsive and I cannot even switch to a virtual terminal in order
to login again.
I have to press the power button in order to initiate a shutdown of
the machine...

I hope you can reproduce the bug and fix it and/or forward my bug
report upstream.

Thanks for your time!
Bye.
