I didn't know we had Sentry! How can we get crash reports from KDE Connect through it? That would be super useful. I've used Sentry in the past for other projects and I see a big value in it.
Actually, in the case of the KDE Connect Android app, we already get crash reports aggregated by popularity by default via the Play Store. Same with the Windows version published in the Windows Store. It's very useful to fix the most common crashes, and it would be great to have something like that for Linux as well. About the alternative of using bugzilla for crashes: We can't know how common a crash is with the crashes that seldomly get uploaded to bugzilla. So +1 for keeping Sentry.
