This is probably (indirectly) caused by https://github.com/ActivityWatch/aw-qt/issues/49

@wuyudi Holy moly. Sorry about that.

PRs welcome! (I'm afraid I'll keep procrastinating on this otherwise)

[ErikBjare]

The following PRs should make sure this never happens again:

• Rotating logfiles with max size: https://github.com/ActivityWatch/aw-core/pull/114
• Handle the errors better: https://github.com/ActivityWatch/aw-watcher-window/pull/73

Thanks for reporting @ivanpondal & @wuyudi!
