File upload mimetype validation fails for csv

[GoogleCodeExporter]

Basically the problem seems to be that Chrome webdriver does not assign the 
right mimetype to csv files during Selenium tests. This causes my jQuery file 
validation to fail, even though the exact same file works during manual tests, 
and the test passes with the Firefox webdriver. (I would be happy to be proven 
wrong, though, with another root-cause provided).

What steps will reproduce the problem?
1. Have file validation using jquery-validation library (available here: 
http://jqueryvalidation.org/). Restrict file extensions and mimetypes to csv. 
Code below:

$(document).ready(function() {
    'use strict';
    $('#grade_form').validate({
        rules: {
            grade_file: {
                required: true,
                extension: "csv",
                accept: "text/csv,text/comma-separated-value,application/vnd.ms-excel,application/vnd.msexcel,application/csv"
            }
        }
    });
});

2. Using Selenium and Chromewebdriver, attempt to upload a csv file to that 
input.

    file_input = self.browser.find_element_by_id('grade_file')
    file_input.send_keys('/<FULL_PATH>/grades_deid.csv')

    grade_form = self.browser.find_element_by_tag_name('form')
    grade_form.submit()

3. Receive error about incompatible mimetype during test. Test fails / 
times-out waiting for next step

What is the expected output? What do you see instead?
File should upload and test should continue. This works just fine in manual 
tests using Chrome 29.0.1547.57 and the same csv file.
Instead, during the test, the input gives me an error (see attached 
image)--Please enter a value with a valid mimetype. This also works fine using 
the Firefox webdriver...

Selenium version: 2.35.0
OS: Mac OSX 10.8.4
Browser: Chrome, Firefox
Browser version: Chrome 29.0.1547.57, FF 23.0.1

Issue is reproducible with chrome: 41.0.2272.76 and chromedriver:2.14. But when 
tried to select file manually, issue is not reproducible

please have below java code:

WebDriver driver=new ChromeDriver();
driver.get("evalidatetest.html");
driver.findElement(By.id("grade_file")).sendKeys("TestCsv.csv");
driver.findElement(By.tagName("form")).submit();

I've run into this problem myself in my selenium tests. I believe that the 
error is caused by the fact that chromedriver assigns the mime-type 
'application/octet-stream' to every file that it uploads, so your application 
will not be getting the mime-type that you expect it to.

I'm supporting the Selenium2Library for Robotframework and a user reported this 
issue to me as well. They reported the same behavior on Chromium 41.0.2272.76 
(webdriver 2.15) and google-chrome-stable 42.0.2311.135-1 (webdriver 2.15).

This issue happens due to devTools DOM.setFileInputFiles

Is there any workaround for this issue?

I also receive this problem when using ChromeDriver to upload a .doc or .docx. 
Chrome cannot seem to detect the correct mime-type of the file so is using 
application/octet-stream
