Bleachbit freezes upon trying to wipe free space


I recently upgraded from Bleachbit 2.2 to version 3.0. The system is running 64-bit Linux Mint 19.1.

In the newer version, my Bleachbit is freezing up when I try to use the wipe free space function. The message shown is "Loading native cleaners", but Bleachbit locks up after this message is shown and I can't do anything else. It takes a force reboot for me to get Bleachbit to respond again; even after killing Bleachbit, I can't reopen it. I did not have this problem with version 2.2.
