Hi, Mark

Thank you for the info.

I confirm that downgrading the following packages to 1.8.3-3:

libx11-6
libx11-data
libx11-dev
libx11-xcb-dev
libx11-xcb1

fixes completely my (fvwm) window manager crashes.

I have marked on 'hold' the above packages to prevent upgrades until it gets fixed.

A huge number of packages depend on this library, so I hope the regression will be addressed.

Stefan
