[Users] Mbox import has failed.

[Adrian]

I'm trying to import an mbox file (you guessed?)

And I get this error.

Now, I don't exactly blame Claws Mail for that.  To be honest, I've
faked up the mbox file by concatenating select individual mails from
other mbox files, and may have got something wrong.  The mails are not
in date order, for one thing.

But I really would like an idea of what Claws itself thinks is wrong!

Any ideas?
