Xubuntu's Thunar is in my opinion a great program, but when selecting "Extract Here" in the context-menu that appears when right-clicking on an archive file (.zip etc) there is sometimes a program crash instead of extracting the file. This has actually nothing to do with Thunar, and there is a way to fix this.
Edit the file gnome-file-roller.tap which on my machine is located here:
/usr/lib/x86_64-linux-gnu/thunar-archive-plugin/gnome-file-roller.tap
Replace:
exec file-roller "--extract-to=$(pwd)" --extract-here --force "$@"
With:
exec file-roller --extract-here --force "$@"
