You have some message where there's some garbage data in header? Or
probably in some MIME part header. And the header is over 130kB long?
That's a bit weird. My guess is it's a broken mail.

There's anyway a bug since it shouldn't be crashing even with garbage
input.

Do you still have this message available? You can probably find it with:

doveadm fetch -u username 'mailbox size.virtual' uid 37

And seeing if that's a >130k message somewhere in the list. If that's a
spam or otherwise a message you can send me, it would help fixing this.
