Hello, I have 2 Fedora Core 4 servers with python-2.4.1-2
I installed the graphviz plugin for trac (I have trac 0.9.5) On the
first server everything went smooth without any problems. However on
the second server after doing everything just like on the first one I
get this error when trying to use graphviz: Trac detected an internal
error: [Errno 32] Broken pipe

Please help
Thank you
That's an interesting problem, haven't seen it with the Graphviz
installations that I use. I'm wondering if there's a problem of some
sort with launching graphviz programs (dot, neato, etc) from Python's
os.popen3 call.
Are you able to run the graphviz programs from a command line? What
version of graphviz are you running? (dot -V)
I currently don't have a Fedora system installed. Let me create Fedora
installation and see if there's anything that jumps out...
