398958 - JS exception dragging image

Status: RESOLVED DUPLICATE of bug 393627

Description

[Josh Aas]

Using current trunk debug build, repro steps:

1. Set home page to "http://www.mozilla.org/projects/minefield/"
2. Open browser
3. Drag Minefield bomb icon in top-left of page
4. See exception in console

************************************************************
* Call to xpconnect wrapped JSObject produced this error:  *
[Exception... "'Component is not available' when calling method: [nsIHandlerService::fillHandlerInfo]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "<unknown>"  data: no]
************************************************************

Not all images produce the exception, just some.

Actually, I think this happens with all images. What I thought was an image not producing the  exception was not an image.

This sounds like yet another instance of bug 393627.

Indeed. Probably called via nsTransferableFactory::Produce which calls nsOSHelperAppService::GetFromTypeAndExtension which calls nsHandlerService::fillHandlerInfo.
