Public bug reported:
Binary package hint: thunderbird
Summary: Thunderbird should eliminate bad entries in the mimeTypes.rdf
file, especially the one that in some cases links .doc files with the
mime-type "text/richtext".
Longer explanation:
Attaching .doc documents (MS word format, can also be saved by OpenOffice.org)
causes the (binary) contents of the file to be displayed inline (like body
text): plenty of weird characters, hundreds of question marks etc (see below
B.).
Primary reason: In (my and other people's) mimeTypes.rdf, there is an
entry that makes TB think that .doc files are of the mime-type
"text/richtext", instead of "application/msword" (see below A.).
"text/richtext" attachments are displayed inline, "application/msword"
attachments not.
Removing the tag <NC:fileExtensions>doc</NC:fileExtensions> and
restarting TB fixes the problem.
This does NOT happen with a fresh profile, because it does not contain
the corrupt entry. But still, users suffering from this problem should
be helped automatically. The GUI does not offer a solution for this, as
far as I know.
A. The corrupt entry from mimeTypes.rdf:
<RDF:Description RDF:about="urn:mimetype:text/richtext"
NC:value="text/richtext"
NC:editable="true"
NC:description="Microsoft Word-Dokument">
<NC:fileExtensions>doc</NC:fileExtensions>
<NC:fileExtensions>rtx</NC:fileExtensions>
<NC:handlerProp RDF:resource="urn:mimetype:handler:text/richtext"/>
</RDF:Description>
