urxvt and urlLauncher not working

I recently found myself having problems with urxvt. In my configuration-file, .Xdefaults, I had the following lines set up:

URxvt.perl-ext-common : default,matcher
URxvt.urlLauncher : /usr/bin/google-chrome

This would enable urxvt to highlight a link in white, and when clicking it would launch the URL in to a tab of my browser of choice. But one day it suddenly stopped working, for no apparent reason. After a little digging, I found the following in urxvt’s changelog, http://cvs.schmorp.de/rxvt-unicode/Changes:

– INCOMPATIBLE CHANGE: renamed urlLauncher resource to url-launcher.

Changing URxvt.urlLauncher to URxvt.url-launcher in .Xdefaults seemed to fix the problem!
