Bug#975039: Evolution 3.38.1-2 fails to render emails: WebKitWebProcess crashed. Sandbox

[Kai Juse]

I noticed my last reply did not go to BTS...

Today I re-checked by upgrading evolution again.
ii  evolution                      3.38.2-1     amd64
ii  evolution-common               3.38.2-1     all
ii  evolution-data-server          3.38.2-2     amd64
ii  evolution-data-server-common   3.38.2-2     all
ii  evolution-plugins              3.38.2-1     amd64

I also noticed that bwrap is no longer SUID root (and newer
modification time). Re-installing bubblewrap did not change it.

# ls -la /usr/bin/bwrap
-rwxr-xr-x 1 root root 59680 Jan  3 15:13 /usr/bin/bwrap

The observation of the issues has changed slightly with the new
evolution version: Now no window appears at all when selecting "New
message" (in fact, nothing appears to happen). I tried again with bwrap
SUID root (and a reboot for good measure) to no change in behavior.

Back to 3.36.4-2.
