そんなエラーが出てました。正式リリースでサポートされるまで待つということで。
ERROR [2008-08-15 20:04:46Z]: Mono.CompilerServices.SymbolWriter.MonoSymbolFileException: Cannot read symbol file `/usr/local/lib/mono/gac/Mono.Cairo/1.0.5000.0__0738eb9f132ed756/Mono.Cairo.dll.mdb'
結局monoコンパイラとデバッガのバージョンが合ってないんですよね。
SVNからのbz2塊をとってきただけなので、運が悪いのだろうと。
ちょいと古いmdbならデバッグはできるんですよね。
