gpio faild to add edge detection

Hi,

i´m writing a service addon under libreelec (milhouse) and kodi 18 alpha to read push buttons.

gpio access works well on reading and writing gpio pins.

But interrupts didn't work.

GPIO.add_event_detect(23, GPIO.FALLING, callback=btnhandler,bouncetime=300)

throw the above error message.

i tried RPi.GPIO 0.62 and 0.63

I run a test outside kodi. Same problem.

any help ?

after a fresh libreelec installation add_event works well.

Before i´ve only updated from openelec.

May be one of the installed plugins caused it.
