IIRC I saw a thread with the same problem here yesterday. Please search for it, it could help you (and we would not have x threads about the same problem ).
I just did an update with yast and it let me to choose between three options. I selected “downgrade” because even if the version in update repo is 4.2-9.3.1 and the version installed was 4.2-9.17.1, the first has been built yesterday. The update went well.
