This fault was found first in Libreelec 7.90.009 build. Now I retested with the RC2 on Windows and the same problem is present there. Earlier versions work fine.
When opening a particular webradio station Kodi freezes. The only recovery is Kodi process kill then restart. The reproduction rate is 100% with this webradio station.
Kodi log covering the fault occurence can be found here.
I am using Radio addon to browse and open stations. The particular station is called “90.9 Jazzy rádió” which can be found in the Hungarian folder of the addon. The url is: http://94.199.183.186/jazzy.mp3
Not this is the only station suffering this problem. All stations I found producing this fault have Hungarian accented characters in their name, however not all stations having such characters in the name suffer this issue.
Update: the problem seems not related to international characters. The fault is still present if these characters are removed from the name.
