Cannot reproduce this on any of my test machines.
Do you have an Xorg logfile or lightdm logfile?

I can reproduce it on testing, not on stable:

/usr/bin/lightdm-gtk-greeter
/usr/bin/lightdm-gtk-greeter: symbol lookup error: /usr/lib/libpangoft2-1.0.so.0: undefined symbol: hb_font_set_synthetic_slant

Pango got published automatically, having an ABI breakage in gtk..

Ah, this post here is way out, in the meantime lightdm broke 10 times.. :-)

/usr/bin/gtk-query-immodules-3.0: symbol lookup error: /usr/lib/libpangoft2-1.0.so.0: undefined symbol: hb_font_set_synthetic_slant

This means pango has an ABI breakage with harfbuzz. Rebuilding both harfbuzz and pango..

Looks ok again..

Root cause was a pango slipping to stable without harfbuzz:
