### qBittorrent version and Operating System
See above.

### If on linux, libtorrent and Qt version
See above.

### What is the problem
See above.

### What is the expected behavior
No crash on any button Yes/No/Never.

### Steps to reproduce
Don't know wich torrent is causing this, so can't examine payload. 

### Extra info(if any)
This is the 3rd time I see this, crash report above on click on 'Never', on window 'Do you want to download the torrent inside the torrent' or similar, capture mentioned 'Recursive'. For sure not observed on the last beta before v4 and before. First time on v4.03 (previous 2 time on v4.01; did not add too many torrents since last beta, but can't tell if it is 1 of the new torrents). Nothing regarding this is in the LOG.

Having this occur as well when trying to select any of the options with qB 4.0.3 on Ubuntu 16.04.
