Error: Image is invalid or non-existent.

After updating to MW 1.25, updating and installing these packages:

 "mediawiki/semantic-forms": "^3.3",
 "mediawiki/semantic-media-wiki": "^2.2",
 "mediawiki/semantic-result-formats": "^2.1",
 "mediawiki/graph-viz": "*",
 "mediawiki/image-map": "@dev"

I see

Error: Image is invalid or non-existent.

Here's what I see in the logs:

[Thu Jul 02 09:00:04 2015] [error] [client 199.166.207.207] PHP Warning:  Missing argument 4 for GraphViz::graphvizParserHook(), called in /opt/webs/su.nicer.info/docs/mw/extensions/SemanticResultFormats/formats/graphviz/SRF_Graph.php on line 115 and defined in /opt/webs/su.nicer.info/docs/mw/extensions/GraphViz/GraphViz_body.php on line 784, referer: http://su.nicer.info/mw/index.php?title=Main_Page&action=edit

fwiw, the platform's dot - graphviz version 2.26.3 (20100126.1600)

Thanks.

Despite the error messages, I discovered the problem was an out of date $wgTmpDirectory so it's working now.
