After the big update yesterday, some people reported some problems with NetworkManager-applet and nano on LQ. Pat finally pushed small update today to fix those problems and also include another update on llvm as well.
The file is now downgraded to 5.11, which is working fine with other applications. I tried upgrading to 5.14, but the problems with libmagic persists, so i think it's safer to wait for another release before attempting to upgrade this.
NetworkManager-applet is now rebuilt to add patches with newer GTK+ libraries which were upgraded yesterday.
Things should be functioning normally again :)
