Error in parsing Euronews RSS feed

[demetera]

When I parse RSS feed : https://www.euronews.com/rss?format=mrss&level=theme&name=news

I get an error:

fatal.nim(54)            sysFatal
Error: unhandled exception: index 8 not in 0 .. 7 [IndexDefect]

While parsing similar URL feeds is successfull.: https://de.euronews.com/rss?format=mrss&level=theme&name=news https://hu.euronews.com/rss?format=mrss&level=theme&name=news

I'm using FeedNim.getRSS(url) method.

I didn't find any differences in the content, which is really confusing me. Thanks
