Overall summary

Files don't save on Signal on Linux 7.12, 7.11

Steps to reproduce

1. Receive a file (playable video OR text MIME)
2. Click on Save
3. Dialog pops up to save file, click save
4. Dialog closes, nothing happens.

No file is create locally of any length.

NB!!! The Debug Log doesn't save locally either. So it looks like a global UI problem.
