Solidity 0.4.24 events - System Error when running Ganache 2.0.0-beta.2 on darwin

[matthieu-merlyn]

Deployed a few contracts (solidity 0.4.24) and executed some functions here and there.
Error is thrown as soon as I want to take a look at the events triggered by those functions, using the Events link in the top menu bar. However, when I first go to the contract itself and then click on the event no error is thrown.

Contracts are loosely based on ERC20 Token and Crowdsale definitions of OpenZeppelin 2.0.1
Truffle project linked with truffle-config.js file

PLATFORM: darwin
GANACHE VERSION: 2.0.0-beta.2

To make sure we're understanding you correctly: The error is thrown when trying to view the event via the Events page, but can be viewed successfully if accessed through clicking the event in the single-contract view?

Potentially related to #1140.
