I have an instance of sitecore 8.0 setup (CD and CM separate servers).
On the CM server we've noticed that if a page has multiple versions, and a user then tried to mark one of the versions as unpublished we get an error on the server itself: An unhandled Microsoft .Net Framework exception occurred in w3wp.exe and iis will restart. The change does actually go through but with the app pool refreshing whenever this happens its making publishing and unpublishing and extremely long process.
Is this something anyone else has faced before, any suggestions on where to look further?
I've exported the process as it crashed and ran in through debugdiag to get the following:

inside the log files we see:

Thanks in advance!
<DataFolder>\tools\phantomjs\phantomjs.exefile exists. There is also asc-ee.jsfile in that directory next to phantomjs.exe.<web root>\temp\screenshots. I would double check those three things prior to going to support. If it solves your problem, I'll add it as an answer.
