Barring any unforeseen problems, we expect the 0.11 system for
profiles to remain compatible from now on. We have a plan to make it
easier for new projects to provide IPython profiles in *their own
tree*, but the syntax would be backwards-compatible. Whereas now you
say
ipython -p profname
we'd like to allow also (optionally, of course):
ipython -p project:profname
which would search in the installed tree of project, a subdirectory
called ipython/profiles/ for that profile name. This would let
projects offer and update their own profiles without users having to
install anything in their own ~/.ipython directories. But that's not
implemented yet :)

That's a bug, plain and simple, sorry :) For actual code, instead of
exec_lines, I use this:
c.Global.exec_files = ['extras.py']
that way I can put everything I want in a file, and I can also load
that file from my old-style profiles. My new-style profile consists
of very few lines these days, just setting a few startup options, and
I leave the heavy lifting to my little 'extras' file.
Does this help?
Cheers,
