I am using openSuse Tumbleweed in Italian.
When issuing a 'zypper dup' command, if there are conflicts it reports the
conflict message in an incomplete fashion.
If I force the English language, it is reported correctly.

e.g. this is in Italian:
> [ cristiano@xmper8q3 ~ ] sudo zypper dup
> Calcolo upgrade di distribuzione in corso...
> 4 Problemi:
> Problema: problema con insync-dolphin-1.3.12.36116-fc17.noarch installato

This is in English:
> [ cristiano@xmper8q3 ~ ] LANG=C sudo zypper dup
> Computing distribution upgrade...
> 4 Problems:

As you can see, when reporting "Solution 1" in English zypper reports the
replacement package name and vendor and the replaced package name and vendor.

In Italian the replaced package name and vendor is missing and also there are a
few spaces and words missing. The Italian message it should be:
>  Soluzione 1: installa insync-dolphin-3.4.2.40983-1.noarch dal fornitore @e73ead5e6ad0 in sostituzione di insync-dolphin-1.3.12.36116-fc17.noarch del fornitore luis@luis-VirtualBox
