I've been monitoring this for weeks, and today it has set it's minimum value for at least the last five years, which was for € 7.96, on the close of Feb 12, 2009, as can be seen in the graph below (from Bloomberg). The dive seems clearly related to the Climategate 2.0 revelations, since it closed at € 9.04 on Tuesday, diving more than 20% since then. These are definitely good news for Durban...

Update: 16:30 CET The minimum price was reached slightly after this post was published, at € 6.95, but has been recovering since then, halving the loss.
