[Mike Pinkerton (not reading bugmail)]

well, this is probably an xpcom problem. reassigning to dp and changing
component.

Comment 2

[Suresh Duddi (gone)]

Mozilla registry is the profile registry. Component registry is the xpcom
registry. Passing to selmer.

adding some mac guru's, in case others are seeing similar bugs or have guess.

I'll continue to debug this.

all praise sfraser.

I was way out of my mac debugging league, so he did the debugging and I watched.

we found that there are some problems with nsFileSpec.

they are:
1) not propagating errors when doing a += on a bogus fileSpec that already has
error set.
2) not consistently nuking some of the private member variables.

we run into these problems because loading the hidden window causes us to try to
init the global history (and probably bookmark service) which calls the file
locator which calls into profile.  there is no registry, which means there is no
profile, which means there is no profile directory.

in short, boom.

he's gracious offered to fix the problems we saw in nsFileSpec, to allow the
error to be propagated and all to go well.

rjc and I are going to meet and discuss how change the hidden window to not look
for history.dat and bookmarks.html, but the problems in nsFileSpec still need to
be fixed.

to repay sfraser help, I'm bringing him some Guinness.

all praise sfraser.

Comment 6

[Mike Pinkerton (not reading bugmail)]

all praise sfraser.

seth, regarding having the hidden window not loading bookmarks/etc, why not just
defer the loading of the hidden window until we have a valid profile? We really
need the hidden window to have bookmarks/etc in it for Mac.

all praise sfraser.
