[Spacewalk-list] tracebacks with libzypp-16.5.2 on SLES-12.2

Thu Apr 6 11:19:17 UTC 2017

Hi,

My SLES-12.2 servers started to trigger tracebacks via XMLRPC since libzypp was updated to libzypp-16.5.2-27.9.1.x86_64.

I think the following commit changed libzypp to trigger these exceptions:
https://github.com/openSUSE/libzypp/commit/27848e716ce912bc437493e2fc941c7a84261c3d

My question: Is this a bug in spacewalk or in libzypp?

some stuff from the traceback:

Exception type <class 'spacewalk.server.apacheRequest.UnknownXML'>
Exception while handling function media.1 Request object information:

Before the libzypp update I could only see access attemtps for "/media.1/media" when rpm packages were downloaded from my SW-server, but these attemtps did not trigger exceptions on the SW-server.
I can reproduce this with every "zypper ref" on any SLES-12.2 with libzypp-16.5.2-27.9.1.x86_64.

Bernhard
