Hi! Alfredo: Jep, did that. GDB was how I figured out things went wrong in FreqDisplayForm::setFFTSize() in the first place :). Jörg: Interesting; but the error is quite reproducibly at the same place; I'll try to set a breakpoint at the kernel call and see if that happens again. But that will require some gdb magic (so that GDB only interrupts program flow when the fft size changes), and that's definitively something that would be worthwhile to learn, however I'm postponing this for now for reasons of time available.
