Okular cannot open .cbr files. It complains about being not able to find the unrar while unrar is present and working. I suspect it tries to verify if unrar binary is correct unrar but fails because unrar being non-GNU software does not respond good to "--version" argument. My proposal is to remove that redundant check and live happily and forever. Reproducible: Always Steps to Reproduce: 1. Have rar or unrar installed 2. Open .cbr file with okular Actual Results: Okular says it cannot find unrar Expected Results: Read comics.
