Comment 1 Kevin Fenzi 2012-03-04 15:04:25 UTC

unrar support is not provided in Fedora due to legal reasons. 

You can try installing unrar from rpmfusion...

Comment 2 Dario Meloni 2012-03-04 15:58:57 UTC

I was thinking of adding a try catch to report and error, instead of leaving the exception generate an abrt report.

Comment 3 Kevin Fenzi 2012-03-04 19:36:19 UTC

Well, it's a bit of a moving target... upstream has no desire for this sort of patch (since they ship libunrar), and the refactor this code from time to time. ;(
