When I want to add a layout in the __init__(self) function, the program crashes. Sometimes it takes a few seconds. I also get a different error message every time, for example:
double free or corruption (fasttop)malloc(): memory corruption (fast)malloc(): invalid next size (unsorted)
So there seems to be a memory problem.
Full program:
