friture-0.43-20210128.AppImage, Ubuntu 18.04
Launching from command-line. Friture opens to the main window. I can use mouse for most operations, but pressing any key (even Shift) causes it to close with "Segmentation fault" message. I can use Friture for the purpose (it does process correctly the active audio, routed via JACK to system), just remember not to press any keys. Also for some reason the processing ceases completely after a while, even though the audio is still live, as if Friture somehow loses connection to the device.
Below is the contents of ~/.local/share/Friture/friture.log.txt after a key press or after just closing the new window with the mouse (X):

$ ./friture-0.43-20210128.AppImage
