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.
