Initialization of sensor fusion sometimes hangs in MPL3115_Init ?

I have noticed from time to time my application hangs on startup using the sensor fusion. I first suspected my code but then I noticed something.

After several seconds of execution, pausing the execution with the debugger reveals that the program is looping forever in MPL3115_Init, waiting for I2C callback to send the 'sent' flag

Debugger shows that MPL3115_I2C_Error is 0

 

I am using KL46Z

My code is not interacting with any of the sensors or I2C so far.

Any idea of what is going on ?
