Please use M-x ein:dev-bug-report-template
to write a bug report. It pops up
a buffer containing system information and instructions for submitting a bug
report.
Did you try the same thing in a normal IPython notebook, i.e. from the browser interface?
There is always the possibility of an unintended interaction with another package, so to elimate this possibility the best way is to start EIN in a clean Emacs (i.e., without your configuration).
You can use zeroein.el to start EIN in a clean Emacs. See the Quick try section in the manual: http://millejoh.github.com/emacs-ipython-notebook/#quick-try
Remove all *.elc
files from EIN source directory and its dependencies. Then
restart Emacs and try to reproduce the problem.
You will have problem with compiled files if they are older than the source files and/or the files are compiled with different Emacs versions.
Sometimes you accidentally load libraries from unexpected location, if you installed it in different places in the past or another Emacs lisp libraries you are using bundles the old version of the libraries.
To make sure that all EIN dependencies are loaded from the intended
place, use M-x locate-library
. Also, M-x ein:dev-bug-report-template
does it for you for all EIN dependencies.
Please consider putting log and backtrace in your bug report. Follow the instruction in the manual: http://tkf.github.com/emacs-ipython-notebook/#reporting-issue
