Help Android 5.0: External SD is suddenly called "/body>^J</ht" in Android file picker

[SoWhy]

Hi there,

I recently upgraded my LG G3 to Lollipop with root. Today I noticed something strange: When using the Android file picker to choose a file, it will not show the external SD card as

/storage/external_SD

but instead display

/body>^J</ht

Screenshot:

The storage works fine otherwise. I can't figure out though why those weird characters are displayed.

Anyone know of a reason?

TIA
