Description

Starting with Redmine 3.0 all PDF attachments beeing uploaded are stored in the database with the wrong mimetype "application/force-download" instead of "application/pdf".

This is my redmine3 dev installation which I run on a mac:

Environment:
  Redmine version                3.0.1.stable
  Ruby version                   2.0.0-p481 (2014-05-08) [universal.x86_64-darwin14]
  Rails version                  4.2.1
  Environment                    production
  Database adapter               Mysql2
SCM:
  Subversion                     1.7.19
  Cvs                            1.12.13
  Git                            1.9.5
  Filesystem                     
Redmine plugins:
  redmine_lightbox2              0.2.2

This happens for drag&drop uploads as well as for "normal" file uploads to tickets.

It seems as if this also results in the following webrick warning when trying to download a PDF attachment:

[2015-03-20 19:37:04] WARN  Could not determine content-length of response body. Set content-length of the response or set Response#chunked = true

This warning also appears for images when beeing downloaded.

This seems to be a browser issue. Redmine just stores the content type that is sent by the browser. What is yours? Can you check the headers of the request that is sent when uploading files?
I have just tested with 3.0.1 and Firefox 36, PDF uploaded by selection or drag'n drop are stored with application/pdf content type.

this is part of the redmine 3.0.1 log for a PDF upload in Firefox 36.0.1 on mac yosemite 10.10.2:

This is the firebug network report for a similar drag&drop upload:

This is weird as it works for you in Firefox36 and not for me.
Although, for redmine 2.6.3 it works well with Firefox36 - but the query string doesn't contain the content_type parameter anyway.

And finally, it seems to work well in Chrome 41:

Processing by AttachmentsController#upload as JS
  Parameters: {"attachment_id"=>"1", "filename"=>"test.pdf", "content_type"=>"application/pdf"}

Disabling all firefox addons doesn't help. Still the same issues.

Alright, this seems to be a Firefox "bug" (at least I'll refer to it as a bug, the developers don't) discussed in https://bugzilla.mozilla.org/show_bug.cgi?id=373621

Note 45 seems to give an explanation why this is happening and Comment 59 summarizes the thread with the suggestion to delete the file mimeTypes.rdf in your Firefox profile folder.

This helped and I'm no longer experiencing the issues in Redmine after deleting the file and a Firefox restart.

You can close the issue. Sorry for the trouble.

Cheers,
Tobias
