The following test page: http://www.bath.ac.uk/%7Epy8ieh/internet/projects/mozilla/object-broken.html ...has the following markup: <object data="dead.gif" type="image/gif"> <p>The image could not be fetched!</p> </object> ...but althought dead.gif does not exist, we never show the contents of the OBJECT element. We just show nothing. Note: This may be causing the crash in bug 15018.
Andre, what's happening is that the frame construction code gets notified that the image can't be rendered and it removes the image frame. The object frame code doesn't handle the RemoveFrame() call and so we hit an assert in nsFrame The fix is not to have the object frame code handle RemoveFrame(), because we don't want the image frame replaced, we want the object frame itself replaced and its content displayed I don't want the frame construction code checking for the image being a child of the object, and so the best thing would be for the CantRenderReplacedElement() call to notify the frame construction code that the _object_ can't be rendered After all, the image frame is just an implementation detail of how the object frame code works. To get this right you probbaly need to have the object frame code notified that the image can't be rendered. When you get that notification you notify the pres shell that the object can't be rendered Today what happens is that the object frame isn't in the loop

Isn't this a dup of 797? The basic problem seems to be identical: if there's any reason (unknown MIME-type, missing file, missing 'data' attribute etc.) which prevents the OBJECT from being rendered, the alternate content is not displayed as it should. Please reopen if you disagree. *** This bug has been marked as a duplicate of 797 ***
Nope, sorry, this is a different bug. In 797, the content is displayed. In this bug, it is not. Different cause, different effect. Reopening. Compare the results of these test cases: http://www.bath.ac.uk/%7Epy8ieh/internet/projects/mozilla/object-unknown.html http://www.bath.ac.uk/%7Epy8ieh/internet/projects/mozilla/object-broken.html http://www.bath.ac.uk/%7Epy8ieh/internet/projects/mozilla/object-noattr.html They demonstrate bug 797, bug 15019 (this one) and bug 22047 respectively, see also bug 678.
OK, you must be using a newer build. I cannot see OBJECT content in 797 using the 1999121909 Linux build or the Dec 19 Windows installer build (cannot test on newer builds right now), so I figured that these were duplicates.
WFM on NT.
