  I get following in mmessage buffer : 

Type C-c C-c to toggle between editing or viewing the document.
No PNG support is available, or some conversion utility for ps files is missing.
Error during redisplay: (eval (number-to-string (doc-view-current-page))) 
signaled (wrong-type-argument numberp nil) [2 times]
Unable to render file.  View extracted text instead? (y or n)  y
doc-view-start-process:
  ps2pdf -dSAFER /home/devel/test.ps 
/tmp/docview1001/test.ps-932911a0f86866e1b95b1aaf506a818b/doc.pdf
Error during redisplay: (eval (number-to-string (doc-view-current-page)))

Type C-c C-c to toggle between editing or viewing the document. [2 times]
DocView: process ps->pdf changed status to killed.


Command ps2pdf -dSAFER /home/devel/test.ps
/tmp/docview1001/test.ps-932911a0f86866e1b95b1aaf506a818b/doc.pdf
executed in a console works perfectly ...
