Bugzilla Bug 233458

Output of an emerge pambase, followed by a --fetchonly, follows.  The file
verify is obviously failing due to filesize (that'll be a separate bug), but it
shouldn't be causing a traceback.  This is a narrowed-down case from an emerge
-avNuD system where the traceback caused it to abort even tho I have
EMERGE_DEFAULT_OPTS=--keep-going set.

~amd64, here's a listing of apropos packages (let me know if you need a full
emerge --info, but I doubt you do for this):

$emerge -p bash python portage gcc glibc

These are the packages that would be merged, in order:

fix bug in exit listener logic

If this is saved as /tmp/remove_exit_listener.patch then it can be applied as
follows:

patch /usr/lib/portage/pym/_emerge/__init__.py /tmp/remove_exit_listener.patch

This is fixed in 2.2_rc6.
