[Gregor Riepl]

Package: cura
Version: 4.8-4
Severity: normal
X-Debbugs-Cc: onitake at gmail.com

When loading the zeroconf module, the following stack trace is produced:

UM3NetworkPrinting.src.Network.ZeroConfClient._handleOnServiceChangedRequests
[99]: Exception: Failed to get service info for [_ultimaker._tcp.local.]
[ultimakersystem-ccbdd3003991._ultimaker._tcp.local.], the request will be
rescheduled

This was caused by: https://github.com/jstasiak/python-zeroconf/pull/260

It shouldn't be too hard fix. Here's and example how it could be done:
https://github.com/rytilahti/python-miio/pull/898/files
And it's possibly already fixed upstream?
