apport-gtk crashed with urllib.error.URLError in do_open(): <urlopen error [Errno -3] Temporary failure in name resolution>

[Chris Guiver]

Ubuntu lunar daily (LIVE) test on
- lenovo g560 (i5m-480, 4gb, i915)

Most of session went well; then screen just went black, a white segment (window trying to draw? as large rectangle) then report of crash...

I tried reporting against GNOME-SHELL due to .crash file in /var/crash...

Attempts to `ubuntu-bug _usr_bin_gnom<TAB>` failed due to 502 PROXY ERROR & inability to login...

message led me to believe report would be https://launchpad.net/bugs/2009260 but that maybe wrong)... this was filed later on same box..

This CRASH WITH APPORT maybe related to the 502 PROXY ERROR I obtained.. rather than code on the box I was perform test on.. but that is GUESS.

Note: I was having trouble operating device touchpad (esp clicking) so user input (me) may have been abnormal..

Thank you for taking the time to report this bug and helping to make Ubuntu better.

The GNOME shell crash details can be found in JournalErrors.txt. Can you open a separate bug report for it? This report is about the crash of apport-gtk itself. The stack trace:

This is a duplicate of bug #2008638 which I fixed a few days ago (no release yet).
