53864 - some pages never finish loading

Status: VERIFIED DUPLICATE of bug 53956

(SeaMonkey :: General, defect, P3)

Description

[R.K.Aa.]

Saw this first time in the morning build from the 20th. and it is still going on
in 2000092215 (?)

go to http://bugzilla.mozilla.org
click link "View Bugs Already Reported Today"
the query will appear, all visible, but the throbber never stops and the
progress indicator never "retires". (It's stalled but that's another bug. when
other pages are finished loading it vanishes again however - not so in this case.)

Breaking in gdb and asking "where" - then continue - shows this:

also noteworthy perhaps: if i leave the browser thobbing on "forever" there is
disk activity at regular intevalls. No idea if this is caused by the animation
or if something bang it's head against the wall in cache, trying to refresh the
page there?

Comment 2

[Stephen P. Morse]

Consequence of this bug is that the OnEndDocumentLoad notifications never get 
called so none of the processing required after a document load is getting done.  
For example, password manager and form manager's automatic prefill will not 
occur.  See bug 53956 for more details about that.

There are probably other undesirable consequences of not calling the 
OnEndDocumentLoad routines that we don't know about yet.

Comment 3

[Asa Dotzler [:asa]]

who should be calling OnEndDocumentLoad here then?
