User Agent: Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0
Build ID: 20120228210006

Steps to reproduce:

Drag and drop images into message compose window.

Using current Daily nightly build Mozilla/5.0 (Windows NT 5.1; rv:13.0) Gecko/20120302 Thunderbird/13.0a1

Regression range is unknown.

Actual results:

When message is sent or saved as draft, the images do not show up in the message window. The attachment pane shows an attachment but with unknown file type and no size.

Example of content from view source...

Content-Type: application/x-moz-file;
Content-Transfer-Encoding: base64
Content-ID: <>
Content-Disposition: inline;

Expected results:

Images should display in the message window.
This exists as far back as 2012-02-20
Regression range needs refined.

bug 499008 landed in the regression range.
Ehsan, drag and drop images was fixed for thunderbird in bug 609632
could the new API have broken that fix.
Keywords: regression
Some further diagnostic info:
Here is what the data url looks like in the compose window (before sending)
In a working build:
<img src="data:image/gif;base64
after the regression:
<img src="data:application/x-moz-file;base64
Severity: normal → major
This is also reproducible on  Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20120302 SeaMonkey/2.10a1, in both Mail/News and Composer. Thus, either something is missing in comm-central or it's indeed a Core issue.

Note that drag-and-drop produces a "data:application/x-moz-file" URI whereas copy-and-paste still generates a correct "data:image/..." source.

Additional testing:
Downloaded current Firefox trunk
Found a conteneditable test page on the web
Dragged a local image into that.
The image "appears" normally the same as it does in Thunderbird.
(I found no easy way to look at the source at this point)
Copy/paste that content into TB compose window.
The resulting source is: src="data:application/x-moz-file;base64
Since the actual drag was performed in Firefox, I conclude that the bug is Core.
