--- Comment #11 from Vittorio Zecca <zeccav at gmail dot com> --- You still around, Steven? I cannot say I missed you. Nobody asked me to apply those fixes, I imagined that Tobias Burnus, their author, would try them and eventually apply them. It seems that it did not happen. Anyway, I just applied the patches to the trunk 8.0.0 level 247930 and the ICE disappeared.
