Bug description:
When trying to load Twitter in a new service, an empty page is displayed. Trying to change the URL from https://twitter.com to anything else promptly crashes Ferdi with a segmentation fault.

In contrast, TweetDeck loads correctly, but when clicking the Log In with Twitter button, I get redirected to a https://mobile.twitter.com page, which exhibits the same phenomenon as above. However, if I enter a new URL _before_ hitting to Log In, Ferdi can successfully navigate to it, so navigation isn't broken, only navigating away from Twitter.

Curiously, it is possible to open the Service Developer Tools even on the blank page, where everything seems normal (I can reload the page and check network headers, or start profiling the JavaScript being executed). There don't seem to be any unusual errors in the service console, the Ferdi console, or printed to the standard output.

I was trying to track down the crash, but the sheer size of Chromium and the fact I haven't compiled it with debug symbols makes the stack trace impossible to interpret.

Steps to reproduce:

1. Add a new Twitter or TweetDeck service.
2. Try to log in.
3. Observe the empty page.
4. If a new URL is entered to the navigation bar, Ferdi crashes.

Expected behavior
I can log in to Twitter and Ferdi doesn't crash.

Environment:

• Operating System: Arch Linux Linux 5.9.0-arch1-1 #1 SMP PREEMPT Mon, 12 Oct 2020 18:52:13 +0000 x86_64 GNU/Linux
• Ferdi Version: 5.6.0-nightly.1 d97c00f962757210d7ef617c40d4c4e3da37efb1
• Electron Version: 9.3.2

• Server: Using without an account

• Debug information: I can't seem to be able to copy or publish debug information, but that might just be a misconfiguration of my environment (to reproducibly confirm the bug, I ran Ferdi directly from the source tree).
