Re: [Matplotlib-users] Crash on import with CGI wrapped by PHP--unhappy with .matplotlib directory?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I found a reason for the behavior:

The script was running as user apache, but trying to open /root/.matplotlib,
and /root was mode 0700. It stopped crashing on import after I made /root
mode 0711.

This is somewhat surprising behavior to me; shouldn't it be defaulting to
something besides expected access to ~root?
