Ubuntu: Segmentation fault on any key press and on exit

[nomadbyte]

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

Not sure it's the same or not, but on Ubuntu 20.04:

I have the same error with Friture 0.45-20210328 on Debian testing/Bullseye.

First I had to install Python3-PyAudio manually, as stated on issue #145. Then Friture works bug segfaults when pressing any key

I see the same crash with 20210308 on Mint 20 (mostly Ubuntu 20.04). I already have python3-pyaudio and libportaudio installed.

It does not write anything to the log file before it dies, I waited a while after starting to press a key in the FFT settings dialog.

Build/install from git does not work either pip install gets error, see attached log2.txt

+1 with the segfault, as soon as I type anything (even if it's just a modifier key like ALT to move the window) it's gone. Xubuntu 20.10 here, no useful debug output whatsoever (except "Segmentation fault (core dumped)")
