[Message part 3 (message/rfc822, inline)]

Subject: calibre: fails to start
Date: Fri, 01 May 2020 17:39:23 -0700
Package: calibre
Version: 4.99.4+dfsg+really4.13.0-3
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Caliber fails silently when clicking on icon in menu.  It reports the following error when starting from a bash prompt.

Traceback (most recent call last):
  File "/usr/bin/calibre", line 20, in <module>
  File "/usr/lib/calibre/calibre/", line 73, in calibre
  File "/usr/lib/calibre/calibre/gui2/", line 543, in main
    listener = create_listener()
  File "/usr/lib/calibre/calibre/gui2/", line 514, in create_listener
    return Listener(address=gui_socket_address())
  File "/usr/lib/calibre/calibre/utils/ipc/", line 110, in __init__
AttributeError: 'NoneType' object has no attribute 'cancel'

This behavior began after running an "aptitude update" and "aptitude safe-upgrade" on 4/30/2020.  I didn't notice if
there were python3 packages or calibre packages updated at the time, but obviously something happened at that time.  As
I use Calibre every day, and did use it in the morning and early afternoon on the 30th the cause of the error had to
have happened during the update and safe-upgrade I did late afternoon.
