Status: RESOLVED FIXED

ASSERTION: Placeholder relationship should have been torn down:
'!shell->FrameManager()->GetPlaceholderFrameFor(mOutOfFlowFrame)', file
c:/work/mozilla/builds/ff/trunk/mozilla/layout/generic/nsPlaceholderFrame.cpp,
line 96

Found using a CVS debug build from 7/31 on WinXP during top site testing of 5469
pages. It appears to be new although I don't have good history of logs for full
top site testing.

I doubt this is related to the splitwindow bug, but ccing jst just in case.

Any idea which URL this might have been on?

Sorry, I thought I had included them. These were found in the full top site
scan. (* - reproducible loading individual pages)

Fix

>+    aFrameIn = nsPlaceholderFrame::GetRealFrameFor(placeholder);

Use GetRealFrameForPlaceholder since you already did the GetType check, and
r+sr=dbaron.

Fixed, with that change.
