I met this bug too.  I triggered this bug when I was clicking an YASnippet menu while editing a remove (TRAMP) file via scp.

Information:

- Emacs: at commit 9ee5af315098245d9f58eb5562dca6997cab4426 Dec 14, 2019.  Built by “./configure CPPFLAGS="-I/usr/local/opt/libxml2/include/libxml2/" LDFLAGS="-L/usr/local/opt/libxml2/lib" --with-ns && make && make install”
- macOS Catalina 10.15.2
