By default urxvt uses TERM=rxvt-unicode but I usually override it with 
TERM=rxvt (and problem
appears with default value too). This is infocmp output:

Yes, it is!  Thank you very much!  GPM is running only on machine where I've 
experienced this
problem and now I'm able to reproduce it on both of them.

What workaround do you suggest? I plan to file a bug to gentoo bugzilla but not 
sure about right
category.  Maybe you have patch against ncurses-5.6 (which currently shipped as 
stable) or
it is better to upgrade?  Or we should blame gpm only?

Also I can try to upgrade gpm from 1.20.5 to 1.20.6 and test if problem remains.
