Graphwiz png file not found

[Massimo]

Hi, the graphwiz png file has only a placeholder and is not found by the webserver:

404 Not Found

​http://project/trac/chrome/site/tracworkflowadmin/a9ba01cbc1573b54760e99a4496a24de.png?=1486984262

I'm serving chrome/site directly by Nginx like this:

location ~ /(.*?)/chrome/site/ {
     rewrite /(.*?)/chrome/(.*)/(.*) /$1/static/htdocs/$2/$3 break;
     root    /mnt/data/trac/projects;
}

If this is the reason for breaking the preview, this plugin is the only issue I have with that rewrite.

Configuration issue.

Please ask on mailing list, first.

Also, why .* is used?

location ~ ^/([^/]+)/chrome/site/ {
     rewrite ^/([^/]+)/chrome/([^/]+)/(.*) /$1/static/htdocs/$2/$3 break;
     root    /mnt/data/trac/projects;
}

As it seems to be the only plugin serving dynamic content here, I solved it by:

location ~ ^/([^/]+)/chrome/([^/]+)/(?!tracworkflowadmin) {
  rewrite ^/([^/]+)/chrome/([^/]+)/(.*) /$1/static/htdocs/$2/$3 break;
  root    /mnt/data/trac/projects;
}

Maybe describe this issue in the wiki. Sry, will contact the list first next time.
