Unable to log in since the last rolling update

I skipped lokgging in for a couple of days around the time of the last rolling update & haven't been able to log in since. My system hsn't changed at all, as far as I know, it's a SuSE system with nVidia that has run SL for many months with no problems. A minor DNS issue occured at the same time as this failure, I was unable to get google.com for a few minutes, but this resolved itself quickly and hasn't come back, and I can ping userserver.agni.lindenlab.com no problem now. I have tried manually wiping the cache directory, that's all I could think of.

The log output from the time the connect button was clicked to the time the failure message was opened is reproduced here:

The message Unknown failure within decompression software is the only lead I've got, but like I said, it worked before lol. My system's quite a bare one, with neither KDE nor Gnome nor even XFCE installed, maybe the problem's something to do with that?

EDIT: Whatever was wrong has fixed itself, after about 24 hours.
