But your stack trace shows this called from xterm in an event loop 6

4 levels in libX11
2 levels in libXt
I'd only suspect the caller on a one-level depth breakage.

I don't see any, it's been more than six months without additional details.
(timing/user-behavior/user-configuration all are factors in reproducing this)
