Crash when searching with duckduckgo from toolbar

Summary

Summarize the bug encountered concisely.

It seems that when I try to search using duckduckgo it crashes (Index 0 out of bounds for length 0 error https://share.riseup.net/#vY_eQVrzY2hw_HtVyK0p4A) but when I use the duckduckgo .onion to search it works fine. It also works with start page (regular and .onion). I can manually go to duckduckgo.com and search but using the search bar breaks it. When I set the default browser to startpage I can use the search just fine.

Steps to reproduce:

1. Launch and bootstrap
2. Try searching for something (having duckduckgo as the default search engine)
3. Notice the app crashes with an out of bounds runtime exception
