Rt3.0.4, error displaying .txt attachments

RT Users
1

redhat 8.0, perl 5.8 (vendor), modperl1, mysql 4.0.14 (rpms)

Imported a bunch of tickets and was spot checking them. I noticed that
tickets with .txt attachments break when trying to display them. I gather
the encoding type wasn’t set during the import? .pdf, .doc and .xls appear
to work fine.

If this is more appropriate for rt-devel, let me know.

Ah. interesting. It’s 12:30 am here, but I should be able to update RT
3.0.x to cope with unencoded imported text attachments, and I’ll also
have a look at transcoding the attachments imported from 2.0.x.

oh, and this only happens on tickets that came in through the import. Newly
attached .txt files work just fine. helloworld.txt works and is newly
attached. domains.txt fails. ContentEncoding is the same. ContentType for
both is “text/plain”.

Whether this helps or not I don’t know.
