One participant in Coimbra had problems creating hte singleshell forward model for the beamformer tutorial once he tried to run this:
load segmentedmri
cfg = []
cfg.method = 'singleshell';
headmodel = ft_prepare_headmodel(cfg, segmentedmri);
The code gave an error within
geometry = ft_prepare_mesh(tmpcfg, data);
and returned an empty geometry structure

His Cris, the following works for me. Do you know more about the specific bug? Am I using the correct segmentedmri.mat file?
