There are bugs is older versions of pygobject related to dir() and tab
completion in the interactive interpreter, I suspect you're hitting
one of those.

I can't replicate this crash when using pygobject 2.28.6 and
gobject-introspection 1.38.0, but I have seen similar issues on Ubuntu
12.04 which uses gobject-introspection 1.32.0.

The warning about "GeglChantinvert-linear_c shadows GeglChantinvert_c"
means you have old files in your $PREFIX/lib/gegl-0.3/ directory you
should probably delete.
