Program crash

The program crashes when you try to download the following playlist:

I tried with these settings: download video; mp4; top 720p(third from the top); download subtitles - annotation, Russian.

Without downloading the subtitles crash does not occur. With subtitles crash occurs at the end of the download of the fourth video.

I agreed to submit a bug report, but was taken to the page "414 Request-URI Too Large"
