Think that I fixed this in a recent set of updates. Please reopen if this is still causing issues for you. It was a race arising from geometry updates being called more than they should have been on the molecule. Original comment by: @cryos |

This is with avogadro-0.9.6 and Qt-4.4.3.
Open testfiles/methane.mpo, go to Extensions->Create Surfaces..., hit "Calculate MO", then switch to Isosurfaces tab and hit "Calculate Mesh" -> I get a segfault in QMutex::lock (this=0xa190094) at thread/qmutex.cpp:147:
