Created attachment 289990 [details] testcase Loading the testcase triggers: ###!!! ASSERTION: How could we not have a parent here?: 'mContent->GetParent()', file /Users/jruderman/trunk/mozilla/layout/tables/nsTableOuterFrame.cpp, line 119
Summary: "ASSERTION: How could we not have a parent here?" with <col>, <caption>, XBL → "ASSERTION: How could we not have a parent here?" with <caption>, XBL
Created attachment 289995 [details] slightly simpler testcase Changed the <col> to a <div>.
Attachment #289990 - Attachment is obsolete: true
See also bug 405186, which involves the same XBL binding and also involves tables.
This is the same issue as bug 405186, really: we have a frame in the frame tree pointing to content that is no longer in the DOM tree.
Depends on: 405186
I saw this assertion with a build from last night, and I don't see it now that I've updated. --> FIXED by bug 405186.

Should this testcase become an automated regression test too, or is the one in the other bug sufficient?
Status: NEW → RESOLVED

Resolution: --- → FIXED
I'd check them both in.
