Subject: [devuan-dev] bug#751: Update: crash due to fvwm window manager crash
Hi, Mark

Thank you for the info.

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


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.
