Crashing have also happened on older versions of chrome.

WebUI crashes after some time with either of these two errors:

Web UI has crashed with the following error: "TypeError: Cannot read property 'nicks' of undefined"
Web UI has crashed with the following error: "TypeError: Cannot read property 'country' of undefined"

It has always been crashing when i'm not using the browser.

I found the culprit.

Newer chrome have a flag in chrome://flags, "Throttle Javascript timers in background."
It throttle javascript in the background tabs or non active windows and that breaks webui in airdc.
If i disable the flag it works as normal.

Description in chrome:

Throttle Javascript timers in background.
When enabled, wake ups from DOM Timers are limited to 1 per minute in a page that has been hidden for 5 minutes. For additional details, see https://www.chromestatus.com/feature/4718288976216064. – Mac, Windows, Linux, Chrome OS, Android

This flag is enabled as default in chrome.

Please include the stack trace from the browser console according to https://github.com/airdcpp-web/airdcpp-webclient/blob/master/.github/CONTRIBUTING.md#ui-related-issues

I've released builds with a new UI version that will show the full stack trace without the need to get it from the console. This issue will be closed without further information as I haven't heard of anyone else experiencing the same crash.
