Hm. Maybe I fail to remember another one, but the three-four scandals involving inappropiate money and the Greens: the bonus miles affair, the two affairs involving PR adviser Hunzinger, and the visa affair all predate the 2005 elections.

Of these the visa affair was most serious, but that involved failure to address corruption at the visa issuing offices of the foreign ministry rather than money taken by Green politicians (and the scandal was staked by the CDU with a faint whiff of xenophobia, considering that the decree that opened the way for this corruption was created to fast-track some acute cases, say someone's urgent need for hospital treatment).

From the context, I suspect you mean the Hunzinger-Fischer affair, about a cheque for €10 thousand in 1998. This affair was created by Hunzinger himself, who claimed in a 2005 interview that this was fee paid to soon-to-be foreign minister Fischer personally for a talk before industry leaders, while the Greens declared that it was booked as a normal party donation. The truth is probably halway, at any rate, note that Hunzinger is close to the CDU and has earlier been sentenced for giving false testimony.

For scale, note that almost all donations to the German Greens come from the public office holding members of the party itself.

I agree that the other issue, whether and how much foreign minister Fischer knew of American torture prisons (more precisely: the kidnapping and torture of Germany residents), is more serious. But I note that the questions now more concentrate on the then interior minister Schily and the then leader of Schröder's chancellery, current foreign minister Steinmeier. Also, this is more a Fischer issue than a Greens issue, as the Greens participated actively in pushing for clearing up the cases (Masri, Kurnaz).
