Bug#1070743: glib2.0: Can't type special characters in most applications

[debianuser]

Source: glib2.0
Version: 2.80.0-10
Severity: critical
Justification: breaks unrelated software
X-Debbugs-Cc: ft.alban.hunter at mail.com

After update do 2.80.0-10, I cannot type special (e.g. german umlaut letters)
characters or dead keys in all gtk applications and most applications installed
via flatpak. Electron and qt applications seems not to be affected, as well as
other applications such as weston-terminal. I am unsure if this bug is caused
by glib2.0, but I can't find any other culprit in the list of recently upgraded
packages on unstable
