What does it mean 'offending .nov data'? Should I grep for '.nov'? I
don't know what it is.

I've removed bytecode because I got warnings about zero values in mail.

Strangely on the stack there is a call to 'gnus-active-to-gnus-format'
where in parameters there are two grups mentioned but not the one I
opened and not the one for which mails I get warnings. What do you think
about it?
