Today, I encountered a breakdown of biber for the second time and with no apparent issue. This issue, as well as a fix, has been reported elsewhere reported here.
I wanted to know if there is a permanent fix for this.
For reference, I'using TL2012 with biber 1.2, but this has also occurred on my system previously, most recently in TL2011 with the previous biber. The problem did not arise after the update though and I don't think it's related to it.
