Thanks for the report!  I'd noticed that text attachments occasionally showed up
as application/octet-stream, but never tracked down the code path that led there.

Cvs now has some code for popping up a dialog when a file is attached that
doesn't seem to be utf8/ascii.  Could you test it?

Peter, is the code still there ? How do we get around
gnome_vfs_file_info_get_mime_type() getting it wrong ? (in my tests we don't)

The code is there, but it's used only when the mime-type is text/*.  We just
trust gnome_vfs_file_info_get_mime_type() to get it right.  Do we have any
alternative?

peter, carlos: *ping* - any news here?

(please only use NEEDINFO state if you need information from the *reporter*. thanks. :-)

Content-Type: text/plain; charset=us-ascii; name=bla-bla.txt

I suggest to use current locale's charset.

GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new enhancement request ticket at
  https://gitlab.gnome.org/GNOME/balsa/-/issues/

Thank you for your understanding and your help.
