Subject: metamail: crashes with very long filenames in messages
Package: metamail
Version: 2.7-50
Severity: normal
Tags: patch

Hello,

metamail crashes if a message has a part with a very long filename and the
user interacts to save it under that name, which is clearly visible on the
screen:


metaur@metaur:~/recently$ /usr/bin/metamail < metamail2.txt
From: <metaur@localhost>
To: <metaur@localhost>
Subject: metamail crash bug #2

This message contains raw digital data, which can either be viewed as text
or written to a file.

What do you want to do with the raw data?
1 -- See it as text
2 -- Write it to a file
3 -- Just skip it
4 -- Give another content type

Please enter the name of a file to which the data should be written
