            Bug ID: 4617
           Summary: Displaying messages takes really long, because
                    libravatar plugin delays display of messages while
                    loading avatar .. and avatar is failing badly.
           Product: Claws Mail
           Version: 3.99.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P3
         Component: Plugins/Libravatar
          Assignee: users at lists.claws-mail.org
          Reporter: list2020 at lunch.za.net

It looks like cdn.libravatar.org is giving a redirect to itself, which
redirects to itself, etc.  It's badly broken, but the problem actually is that
claws downloading the avatar is done synchronously, and also that the remote
failure is not recognised.  I removed the plugin (I'm never putting it back,
and I forget how it got enabled) and now mail that took a few seconds to
display display instantly.  I have had this problem for YEARS, but I thought it
was something wrong with my system.

debug logs follow:
