Call for testing: chromium 65.0.3325.146

I found the following warning using debugging:

[8021:8236:0413/194753.217679:VERBOSE1:key_storage_util_linux.cc(53)] Password storage detected desktop environment: GNOME
[8021:8236:0413/194753.218064:VERBOSE1:libsecret_util_linux.cc(101)] Could not load libsecret-1.so.0: libsecret-1.so.0: cannot open shared object file: No such file or directory

Later follows:
[8021:8021:0413/194753.234451:VERBOSE1:key_storage_util_linux.cc(53)] Password storage detected desktop environment: GNOME

Thanks for reporting the issue @jonubulin. I can reliably observe it if I log in to a google account.

I added libsecret-1-0 to the snap and the related message went away, but still no window showing.
I then issued the following command, and lo! the browser started.

snap connect chromium:password-manager-service

I have filed bug #1763829 to track the issue.
