411807 - MIME-type issue with xml-stylesheet and CSS

Status: RESOLVED DUPLICATE of bug 61675

(Core :: CSS Parsing and Computation, defect)

Description

[Brett Zamir]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b2) Gecko/2007121120 Firefox/3.0b2
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b2) Gecko/2007121120 Firefox/3.0b2

After retrieving a document served as application/xhtml+xml and which uses the standard XHTML practice (
http://www.w3.org/TR/xhtml1/#C_14 ) of adding a stylesheet processing
instruction for internal style tags in such a form:

<?xml-stylesheet href="#style_tag_id1" type="text/css"?>

...

<style type="text/css" id="style_tag_id1">
 h2 {color:blue;}
 .cl1 {color:green;}
 .cl2:visited {color:green;}
</style>


I sometimes get the following error (at other times, the same exact document gave me errors instead about the selectors, but I cannot replicate that now):

Error: The stylesheet
http://127.0.0.1:8080/zamir/vres/index.php?langu=en-US#style_tag_id1 was
not loaded because its MIME type, "text/html", is not "text/css".

This error message is also not correct on account of the fact that the document is correctly being served as application/xhtml+xml (as confirmed by Tools->Page Info), if it is using the contentType as a cue.

Errors also occur when I add an additional xml-stylesheet, such as:
<?xml-stylesheet href="/dr_mainstyles.css" type="text/css" media="screen"?>


Reproducible: Always

Steps to Reproduce:
1. Retrieve a document served as application/xhtml+xml with an internal xml-stylesheet reference (labeled as text/css -- labeling it incorrectly as application/xhtml+xml makes the problem go away) and with a style tag with corresponding  id
2. Open the Error Console
3. See the error(s)
Actual Results:  
Sometimes get the following errors (other times, they are about CSS selectors):

Error: The stylesheet
http://127.0.0.1:8080/zamir/vres/index.php?langu=en-US#style_tag_id1 was
not loaded because its MIME type, "text/html", is not "text/css".

Expected Results:  
No errors

Brett I did ask you to search bugzilla for existing bug reports on this issue first. See Bug 267161 and Bug 61675

Thanks for the lecture, but I did search and found nothing... xml-stylesheet and MIME, xml-stylesheet and CSS... The search engine at this site, Google it is not.

Search a comment -> Change the criteria to contains all of the words/strings. I used "The stylesheet not loaded because its MIME type is not text/css"
Then UNSELECT everything under Resolution.

Here is the resulting query:

I appreciate the tip... I'll try to use the Advanced form next time (hadn't even seen that before)...
