Hi,

the zathura completion which was recently added breaks for me. I have:
-----------------------------
$ ls -1 /usr/lib/zathura/*
/usr/lib/zathura/cb.so
/usr/lib/zathura/djvu.so
/usr/lib/zathura/pdf.so
/usr/lib/zathura/ps.so
-----------------------------
The completion code fails to strip the plugin_path correctly in case the plugin is neither called poppler nor mupdf. 
The attached patch fixes the situation for me. 

I am not subscribed to list, please include me in replies. 

Cheers,
	Oliver
