Crash when reading from timeline

[hannojg]

Describe the bug We just received a sentry crash report which points to the matrix SDK. Our app uses the react-native matrix SDK, thus we can't exactly pin down what caused the crash (we lose the information between the JS side and the native side in the crash reports). All I can provide is the crash report. I hope it helps.
