Form . ErrorReader doesn't work with Form . FileUpload set to true

What steps will reproduce the problem?
1. FormPanel fp = new FormPanel();
2. fp.setFileUpload(true);
3. fp.setErrorReader(errorReader);
4. fp.getForm().submit(urlSubmit, null, Connection.POST, "Uploading
file...", false);
5. Server side, the servlet responding at urlSubmit return :
{"errors":[{"msg":"Error in file","id":"theInputFileUpload"}],"success":false}

What is the expected output? What do you see instead?
 I expect :
Error "Error in file" on field "theInputFileUpload"
 Globaly, my result :
Waiting mask don't stop and continue locking form without errors.

What version of the product are you using? On what operating system?
gwtext-2.0.3
ext-2.0.2
gwt-linux-1.4.61

Please provide any additional information below.
Depending on the cases and browsers :

1/ Servlet return no header and no content
 IE : Waiting mask running loop
 FIREFOX : Waiting mask load and stop but no field error
 GWT BROWSER : Waiting mask running loop

2/ Servlet return no header but content : {"errors":[{"msg":"Error in
file","id":"theInputFileUpload"}],"success":false}
 IE : Waiting mask running loop
 FIREFOX : Waiting mask load and stop but no field error
 GWT BROWSER : Waiting mask running loop

3/ Servlet return header (application/json) and content :
{"errors":[{"msg":"Error in file","id":"theInputFileUpload"}],"success":false}
 IE : Waiting mask running loop
 FIREFOX : Ask to browser to download a file containing the content
returned by the servlet and waiting mask running loop
 GWT BROWSER : Ask to browser to download a file containing the content
returned by the servlet and waiting mask running loop
