After opting into Steam beta Steam client refuses to launch with the error message

Failed to load steamui.so - dlerror(): /usr/lib32/libpangoft2-1.0.so.0: undefined symbol: pango_font_ddscription_set_family

Looks like a typo in the function name? "pango_font_ddscription_set_family"
Not sure if this is issue with the pango library or the steamui one.

Steps for reproducing this issue:

1. Opt into Steam client beta
2. Restart Steam client
