The council is SNP-controlled but all 22 councillors (9 SNP, 9 Labour, 3, Independents, 1 Scottish Socialist) voted for the resolution in 2009. It's interesting that the SNP is not only not boycotting, but is actually giving foreign aid to countries like Pakistan and the Maldives, where the persecution of Christians by Muslims is rife.
Amusingly, this seems to have gone global on Israel-sympathetic sites round the blogosphere. I don't know if any of them have picked up on the SNP's donation of money to Islam-dominated countries that persecute Christians but if they did, it might be a good way of exerting pressure on the SNP about it. All the information is on this site.
