Strange because I have kind of the same experience as Diego...
At least using gtk-- and storing the cairo context obtained at
configure time (maybe not at realization time, I have tried many
variants I do
not remember if I tried that variant), to use it in the handling of
expose events
just did not work. I had to request a new cairo context for each expose
events.
I never had time to fully investigate the problem, but I certainly had a
similar experience...
