maybe-security issue copying symlinks in nautilus

[Arand Nash]

Hello, (sorry if this is; the wrong place/unwarranted/already 
known/otherwise faux pas, but;) I would like to wave a flag for a bug in 
libglib2.0-0, manifesting in nautilus, which may potentially be a 
security issue, since it modifies permissions blackmagically.

The problem is that if copying a symlink using nautilus, the permissions 
of the target will be automatically set to 777 (provided the user doing 
the copying has permissions to do that).
And I'm guessing that unknowingly setting items to world-rw, is 
something that could be a security risk.

Upstream bug report: https://bugzilla.gnome.org/show_bug.cgi?id=593406
git fix commit: http://git.gnome.org/cgit/glib/commit/?h=glib-2-20
Downstream (including debdiffs with quilt patches {created from above 
commit}): https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/418135

Oh, and the issue does exists on libglib2.0-0 2.20.5-1 (squeeze) as well.
