            Bug ID: 343645
           Summary: Treat archive files (.zip, .rar, ...) full of images
                    in the same way as CBR and CBZ files
           Product: okular
           Version: 0.21.1
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: Comicbook backend
          Assignee: okular-devel at kde.org
          Reporter: kdebugs at fratti.ch

Okular fails to open archives full of image files as comic book files when
explicitly told to do so; however, renaming the files to end in either .cbr or
.cbz will make Okular open them without an issue.

Ideally, Okular will ignore any non-image files in the archives, such as
erroneously included "Thumbs.db" files.

Reproducible: Always

Steps to Reproduce:
1. mkdir okulartest && cd okulartest && for i in {0..9}; do convert -size
2480x3508 xc:white -gravity Center -weight 700 -pointsize 600 -annotate 0 "$i"
$i.png; done; cd .. && zip -r okulartest.zip okulartest/
2. okular okulartest.zip
3. mv okulartest.zip okulartest.cbr
4. okular okulartest.cbr

Actual Results:  
Step 2: Okular says it could not open okulartest.zip, and shows the error
message "Can not find a plugin which is able to handle the document being
passed."
The console output reads: okular(5259)/okular (app)
Okular::Document::openDocument: No plugin for mimetype '"application/zip"'.

Expected Results:  
Okular tries to treat the zip file like a cbr file before complaining to the
user.
