193530 - a couple of ways to generate "redundant multiplexed document?" assertions

Status: NEW

(Core :: XUL, defect)

Description

[John Morrison]

There are two cases where I can generate a "redundant multiplexed document?" 
assertion from fastload.

1) some combination of '-edit -browser -mail' on the command line, or the 
   equivalent set in prefs
2) rapidly switching previously unserialized pref panels

Both are a little hit and miss.

###!!! ASSERTION: redundant multiplexed document?: 'docMapEntry->mString == nsnull', file c:/Debug/mozilla/xpcom/io/nsFastLoadFile.cpp, line 1404

Steps to reproduce:

A clean Mac compiled trunk Thunderbird debug build version 3.0a1pre (2008040301) outputs the following on startup:

WARNING: redundant multiplexed document?: 'docMapEntry->mString == nsnull', file /Users/skywalker/Desktop/Mozilla/cvs/mozilla/xpcom/io/nsFastLoadFile.cpp, line 1404
