Hi all,
Someone knows why dextrose (for xo 1.5) restart while you are
downloading something (big) in journal?
The test case is the following:
1. Enter here
http://xoplanet.blogspot.com/2010/08/descargar-open-office-para-xo.html to download
oo4kids (~105MB)
2. Wait and when the download is between 5% or 6% sugar restart and in
the log I can see this message: "python: Modules/gcmodule.c:262:
update_refs: La declaración `gc->gc.gc_refs != 0' no se cumple."
This is sl#2064, which has been haunting us for a while.
See comment 7, it describes exactly the problem you're seeing:

A few days ago I have obtained full a backtrace of this bug on Fedora 14
(so it's not Dextrose specific or 0.88 specific):
http://bugs.sugarlabs.org/attachment/ticket/2064/sl2064-full-backtrace.txt
I have also filed it in Red Hat's bugzilla, but so far nobody analyzed
it:
http://bugzilla.redhat.com/show_bug.cgi?id=640972
I have kept the full coredump of the crashing project, if someone would
like to inspect the variables with gdb.
Another interesting question is: what exactly is the Sugar shell process
doing while a file is downloading? We already suspect dbus, but finding
the exact function call that triggers the bug may let us create a
minimal testcase that triggers the bug quickly and is easier to debug.
