Syntax errors while fetching subs

[Cqoicebordel]

I got a couple of different syntax errors, just after selecting a sub to download. The error is sub dependent, I mean that I get the same error each time I chose a particular sub, an another if I chose another sub.

To reproduce :
$ OpenSubtitlesDownload.py My.Brilliant.Friend.S02E01.The.New.Name.ITALIAN.SUBBED.720p.WEBRip.2CH.x265.HEVC-PSA.mkv

The following popup appears :

If I chose the first or third option, the full output of the command is as follow :

x:  0   y:  0   w:  920   h:  400
/bin/sh: 1: Syntax error: Unterminated quoted string
x:  -1299055440   y:  21854   w:  920   h:  400

If I chose the second, I get :

x:  0   y:  0   w:  920   h:  400
/bin/sh: 1: Syntax error: "(" unexpected (expecting ")")
x:  1160377632   y:  21956   w:  920   h:  400

The fact it's dependent on the subtitle chosen is weird. But it still could come from my machine which is stuck on Kubuntu 20.04.

Anyway, I hope it'll help :)
