no shutdown via q / ctrl-c in 6.5.4

[Mandar Mitra]

I've just upgraded to 6.5.4 on lubuntu 12.04 (via make clean, make, and
checkinstall to create a deb package) and blinkenlights ui has stopped
responding to q or ctrl-c (don't know about the other interfaces). The
default version that's provided by lubuntu (6.3.4) responds fine to both
q and ctrl-c.

Is this a known problem?

Thanks for any tips,
Mandar.
