辻本です。

debug.rbをロードしてvarコマンドを実行すると例外を吐いて落ちます。

$ ./ruby -Ilib -rdebug -e '0'
Debug.rb
Emacs support available.

/home/k_tsj/work/ruby-trunk/lib/debug.rb:150:in eval': can't convert Symbol into String (TypeError) from /home/k_tsj/work/ruby-trunk/lib/debug.rb:150:in block in var_list'

from -e:1:in `'

1.9からKernel#global_variablesなどがシンボルの配列を返すようになったのに
debug.rbが対応できていないのが原因です。

パッチです。
