            Bug ID: 339313
           Summary: Opening PDF results in 36.5% of my 8gb memory used
           Product: okular
           Version: 0.20.0
          Platform: Debian testing
               URL: https://mirror.explodie.org/texts/africa-global-politi
                    cs-pan_african-perspective.pdf
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org
          Reporter: orangewinds at gmail.com

I open the linked PDF, cpu usage skyrockets (I'm going to ignore this for now
and assume it's "rendering" the PDF), and memory usage climbs to 36.5% of my
total ram within seconds. 

memory usage is whatever htop uses for "% ram used". 

Reproducible: Always

Steps to Reproduce:
1. open htop with filter for "okular"
2. open pdf
3. profit

Actual Results:  
Massive memory usage.

Expected Results:  
Some ram used, maybe even 100mb or 500mb, but not 3gb.

I'm rating this as normal, but this would brick some computers (due to distro
maintainers compiling out oomkiller).
