Issue:
Bing Video search engine doesn't work
Hallo,

yesterday I've set up my own instance of searx. Thereby I discovered A problem with the Bing Video search engine. This is the shown error message:

```
Die folgenden Suchmaschinen können die Ergebnisse nicht empfangen:
bing videos (unexpected crash: list index out of range)
```
