I am not exactly sure if it is the same bug that I stumbled upon: The effects were the same, but I thought it was caused by spaces in the file path.
However, attached is a patch (against 1.1-2.4ubuntu1 from Ubuntu 12.04) that quotes the environment variables. The same thing had been done for filenames earlier, but I experienced this issue with the TEXINPUT environment variable, which rubber sets to the directory of the main file.
