# if you forget to install graphviz (the cmdline tools), the WikiFormatting page causes an error

Reported by: Owned by: anonymous pkropf normal GraphvizPlugin normal 0.10

### Description

If you install the plugin in your trac instance but forget to install the graphviz binaries, going to the WikiFormatting page causes a traceback due to GraphvizMacro.processors being empty.

Well, the 0.11 version of the plugin gives the following error in this case:

Graphviz macro processor has detected an error. Please fix the problem before continuing.
The default processor, dot, was not found in [u'C:/Program Files (x86)/Graphviz2.20'].


(here I just removed the trailing /bin from the cmd_path, but a similar error is produced when cmd_path doesn't exist).

Proposing a worksforme here, unless someone wants to fix this for the 0.10 version (if the problem can be confirmed there).
