Updated to 3.19 using Anaconda navigator, from CLI I receive these messages
orange-canvas realloc(): invalid old size Aborted (core dumped) python3 -m Orange.canvas Segmentation fault (core dumped)
Using Anaconda navigator got this log
/home/davide445/.anaconda/navigator/scripts/orange3.sh: line 3: 8261 Aborted (core dumped) orange-canvas > /home/davide445/.anaconda/navigator/scripts/orange3-out-1.txt 2> /home/davide445/.anaconda/navigator/scripts/orange3-err-1.txt
Same problem with 3.20.1 or 3.18, is working using 3.17. Working on Kubuntu 18.04 LTS. Any suggestion for troubleshooting, many thanks.
