RT UI shows an attachment name but no link to it

Hello all,

We have two strange tickets for which RT (3.8.7) shows an attachment
name in the UI, but the history does not provide us with a link to
that attachment.

We will have to dig in the database to get more info. But I was
wondering if an aborted upload would produce such behavior. Has
someone experienced/seen something like that?

Thanks,
Thierry
