Review request for Okular and Albert Astals Cid.


Repository: okular


Description (updated)
-------

Okular refuses to load .cbr files because a `QIODevice` object returned by `KArchiveFile::createDevice()` reports its size to be 0 and because of that `QImageReader` refuses to read. Proposed solution: if that device's `QIODevice::size()` returns 0, copy its content into a temporary file and load image from the file.

Testing
-------

Well, it loads .cbr files now :)


Thanks,

Eugene Shalygin
