I can replicate this error. It must be a problem with permissions or how
the server is configured, or *maybe* with something involving both
permissions and how I made the notebook server secure (by running
all worksheet code as a separate user over ssh). Strange.
I just checked and the problem doesn't happen with the server
on port 8102 for me, but it does for the one on ports 8103 and 8101.
OK, checking the log we have:

OK, I think I've fixed the bug. The particular notebook server that
is running now has
been around a while, and moved around to different directories, etc.
It was once
in /notebooks/server and evidently that path got hardcoded somewhere. Anyway,
I've fixed the problem with a symlink.
