Freezes in Edgy

This patch gives a DefaultException to the errback calls so that errback does not complain that there is no exception at all.

Unfortunately, some unwanted comments made it to the previous patch so here is the correct one.

I can confirm this bug and the patch fix it.

This bug seems fixed in Debian so a simple sync should be enough to fix it in Edgy.

This upload fix that issue.

apt-proxy (1.9.35ubuntu1)

    * Merge from Debian unstable. Remaining Ubuntu changes are:
    * doc/apt-proxy.conf: Set min_refresh_delay=1s.
    * debian/init.d: Use LSB init-functions.
    * debian/install: Install into python2.4 dirs instead of python2.3.

apt-proxy (1.9.35)

    * http_proxy option:
          o Fix import error with option enabled. (Closes: #382171)

          o apt-proxy.conf.5: Document that http_proxy can take a username and password parameter
    * apt-proxy-import:
          o Fix import routine (Closes: #382012)
    * Add translations that got lost in previous version (Closes: #330202, #331515, #336384, #333847)
