I looked at the mails that are still ignored after upgrading GMime to
latest version, and I think I have found what they have in common. All
of my ignored emails are from 2010-2011, and for some reason these mails
contain a line like this:

>From username  Wed Sep 28 16:43:49 2011

somewhere among the headers. Note the '>' at the beginning of the line.
The mails that are still ignored after upgrading GMime are those where
this line happens to be the first line. Also, all of them have
attachments for some reason. That line certainly doesn't look right, and
I don't know where it came from. It might be some byproduct of mail
redirection, since it shows my username, but the mails are not sent by
me.

I moved these problematic lines to the second line of each message, and
now they are imported without problems. I probably won't file a bug for
GMime because I have no idea whether this is just some oddity caused by
my mail setup. Let this information reside here in case someone else has
a similar problem.
