Comment 16 for bug 317366

After actually reading a linked post from ML (It was unavailable before) I've decided to use the same patch that was proposed upstream. Attaching patch and quoting description for further reference as rxvt-unicode doesn't use any patch system. I'll prepare a new debdiff shortly.
