Pressing almost any key twice while hovering over a bond causes a segmentation fault because a text-editor is internally created and discarded but not deleted. When pressing that button a second time this will cause the program to walk down an "unexpected pathway" trying to do something with said editor which finally creates the seg-fault.
A fix for the above exists. As I'm regularly confronted with this issue, and I'm not expecting a new release of xdrawchem anytime soon, I would like to see it fixed in our port. While here take MAINTAINER. OK?
