[Eeglablist] Error while precomputing channel measures

[Fernanda Pérez Gay Juárez]

Hello, Makoto

I was finally able to file the problem to EEGLAB Bugzilla today, with
severity of "blocker" https://sccn.ucsd.edu/bugzilla/show_bug.cgi?id=1840.
Thanks for the advice. I'm guessing there's anything else I can do but wait?

BTW here's bug 764 https://sccn.ucsd.edu/bugzilla/show_bug.cgi?id=764.
