Slow startup when X-forwarding
When running meld over an X-forwarding ssh session, it takes about 30s for meld to start.
See this profile dump: meld-profile.txt
I also tried an strace of the startup, but it produced no output for the majority of the duration.
This is with Meld 3.18.0 on Ubuntu 18.04. I tried to test the latest version, but Ubuntu 18.04 doesn't have GtkSourceView 4.0.
Interestingly, meld --version and meld --help also show this slowness, so it's maybe not an issue with the window display.
