avoid updating (or roll back) gtk3 for the moment (and ideally pin the unproblematic 3.24.27-2), apparently it causes database corruptions with signal-desktop.
Probably won't take long until a fix, but for the moment things seem to be a bit shaky on that ship.
Just as a heads-up:
3.24.27-4 fixes the aforementioned problem by reverting the change in the gtk3-package for now, so updating is unproblematic again for now (if your mirror is not out of sync, so give it a day or two, and keep a look on the version number), freeing time for a hopefully more fundamental fix. :)
