Type error in Service Routine

I randomly get the following error:
Unhandled exception in callback handler TypeError: 'bytearray' object is not callable
Unhandled exception in callback handler TypeError: 'slice' object is not callable
This happens in a callback which is triggerd by a pin interrupt. Defined like so:
The callback function is a very simple method of an object:
def handler(self, arg): self.todo = True
Actually, there is no such type as
bytearrayinvolved in the callback which makes me think its a bug ...
Sometimes the callback works fine for several thousands of times, some times for just a few hundreds.
After that exception the callback seems to be never called again, even tough it should have been called again.
I have a main loop which looks as follows and shall handle the todos:
while True: irq = machine.disable_irq() if this.todo: this.todo = False do_this() if that.todo: that.todo = False do_that() machine.enable_irq(irq) time.sleep_us(1)
Oh yea, forgot to mention:
