142804 - failed fastload(?) crashes remote wizard on second launch

Status: VERIFIED DUPLICATE of bug 142165

(Core :: XUL, defect)

Description

[Axel Hecht]

Using a remote xul:wizard, I get crashes on the second time I try to launch it.
See the one at the given URL, for example. I think it needs to have some 
handlers, the plain example on the wizard.html page seems to work allright.

My debug build asserts all over nsFastLoadFile.cpp. I get varying behaviour,
my own wizard is way more noisy than the example. I don't get a stacktrace 
either, but it exits on a X error. (I'll attach the output)

###!!! ASSERTION: bad call to WriteObject -- call WriteCompoundObject!:
'rootObject.get() == aObject', file /tmp/mozilla/xpcom/io/nsFastLoadFile.cpp,
line 2123
###!!! Break: at file /tmp/mozilla/xpcom/io/nsFastLoadFile.cpp, line 2123

is the first offending assertion, cancel and opening again gives this stack 
trace

forgot, one needs the patch in bug 142502, to have the wizard working at all.
I'm pretty sure that wallpaper in a binding shouldn't do bad things to fastload,
though.

Attachment: more assertions

here is the assertion output I get for my own wizard, with a slightly different

route to failure, started from file:// instead of http://

When did you pull from the trunk for this build. I think this is simply 
bug 142165 which is fixed now in trunk builds as of last night. Um, but
delete you XUL.mfasl file in your profile just to be ultra-clean.

[Axel Hecht]

thanx to John for hinting me at bug 142165, I didn't have that patch in my
tree. I repulled, and this is fixed now.
Resolving dupe, sorry.
