i have build rodeo data oriented ide python:

$ sudo pip install rodeo -u directory '/home/jeanpat/.cache/pip/http' or parent directory not owned current user , cache has been disabled. please check permissions , owner of directory. if executing pip sudo, may want sudo's -h flag. directory '/home/jeanpat/.cache/pip/http' or parent directory not owned current user , cache has been disabled. please check permissions , owner of directory. if executing pip sudo, may want sudo's -h flag. requirement up-to-date: rodeo in /usr/local/lib/python2.7/dist-packages requirement up-to-date: mistune in /usr/local/lib/python2.7/dist-packages (from rodeo) requirement up-to-date: ipython>=3.0.0 in /usr/local/lib/python2.7/dist-packages (from rodeo) requirement up-to-date: docopt in /usr/local/lib/python2.7/dist-packages (from rodeo) requirement up-to-date: pyzmq>=13 in /usr/local/lib/python2.7/dist-packages (from rodeo) requirement up-to-date: flask>=0.10.1 in /usr/local/lib/python2.7/dist-packages (from rodeo) requirement up-to-date: werkzeug>=0.7 in /usr/local/lib/python2.7/dist-packages (from flask>=0.10.1->rodeo) requirement up-to-date: jinja2>=2.4 in /usr/local/lib/python2.7/dist-packages (from flask>=0.10.1->rodeo) requirement up-to-date: itsdangerous>=0.21 in /usr/local/lib/python2.7/dist-packages (from flask>=0.10.1->rodeo) requirement up-to-date: markupsafe in /usr/local/lib/python2.7/dist-packages (from jinja2>=2.4->flask>=0.10.1->rodeo) 

then when rodeo run terminal, things go wrong:

firefox says internal server error

this belongs in comment, don't have rep it, sorry...

but experienced same failure. had rodeo installed via pip on osx , working while (except raw_input() quietly crash whole thing), a) broke ipython notebook independently trying change default file location, 2) uninstalled , reinstalled ipython, 3) somehow rodeo got broken in of this. , got similar errors respect bottom-right.html, although picked differently seemingly random line claim couldn't understand ascii in. (as recall, character claimed confused 'a' -- seriously.)

then randomly came next day. suspect killing , restarting terminal helped. might try that, start.
