Thanks for the report. Indeed, it sounds unfortunate, if you just called 
the command accidentally.

I've pushed a fix (which will make it complain with (void-function nil) 
instead of erasing the buffer) to master. Sometime later, we'll tag a 
new release of the xref package, and you'll be able to update to the new 
version through 'M-x list-packages'.
