This is from a UI test (Bug 1829837), where it pins 3 websites as homescreen shortcuts. After adding the 3rd one and visiting the homescreen, the top sites list is refreshed and all pinned sites are gone.
This happens rarely, approx 1 failure per month, so every few hundred test runs. Not reproducible manually so far.
I couldn't find the crash signature in https://crash-stats.mozilla.org/
