Finnish e-voting results annulled, municipalities to hold new elections by Electronic Frontier Finland ry (Effi), the best summary in English, IMO;

The voting system was provided by Tieto and Scytl. In their News Page, Scytl declares: "Scytl's Pnyx.core successfully used in local elections in Finland" Shouldn't they update this...? It is even possible that the 2% of the votes lost was due to the Pnyx.core, instead of usability issues with the voting terminals, as has been commonly assumed - who knows.

In the Finnish municipal elections 2008, 0.17% of the paper votes were inadvertently spoiled (unclear marking in the ballot ticket etc.) and had to be dismissed. This can be compared with the 2% of the electronic votes lost in three municipalities in which the new voting system was piloted (see Effi's Electronic Voting FAQ, in Finnish).

The total fraction of the spoiled paper votes in the municipal elections was 0.6%. Most of the dismissed paper votes were due to a deliberate action by the voter (votes for Donald Duck - a popular candidate here!, empty ballot tickets etc.). There is no evidence to support the claim that the lost electronic votes were due to a deliberate action by the voters. On the contrary, in addition to the usability problems with the voting machines, there is evidence of system malfunctions which may have contributed to the lost votes (slow response times, freezing of the voting machines during the voting etc.). Additionally, the electronic voting did allow to cast an empty vote.

The original Ministry of Justice announcement (in Finnish) states: "A total of 12234 electronic votes vere cast in the electronic voting pilot of the 2008 municipal elections. - -"

232 is about 2% of 12234 and therefore the summary is correct.

According to the same announcement the total number of votes in the three municipalities in which the voting system was piloted was 21073 (Karkkila 4251, Kauniainen 4843, Vihti 11979), i.e., 8839 of all voters cast a paper ballot. (The voters could choose between the traditional paper ballot and trying the new electronic system.)
