Hangs on changing bond order

[cryos]

Insert cyclohexane fragment or draw it from scratch, with hydrogens added. Start changing bond order in sequence 1,3,5 or similar, 3 bond become double. Then click on any sigle bond - and program hangs.

Possibly that's Eigen bug, but i'm not sure. Avogadro built from SVN.
