Can it be that there's a problem with the builds there? It's crashing right in QML and I do not recognize the backtrace.

I do not know about this, sorry.
Try removing the QML cache: ~/.cache/<app name>/qmlcache
Or rather, move it away. Don't delete it.
Removing the QML cache: ~/.cache/<app name>/qmlcache indeed helped here for Discover and Elisa (here same issue). What do you think was happening here?
It's been a longstanding bug I've been experiencing (often with Mesa updates) in which the QML compiled cache is somehow not compatible and causes crashes. I hope you kept the files, so that at last it can be diagnosed somehow (I'm still not sure it's a Qt bug or a bug elsewhere).
F***, I already removed them :-(, but I can keep an eye on this, I regularly had this issue here. It was solved some time ago and reappeared quite soon.
Either way, this is not a bug in Discover per se, so let's close this.
The issue appeared again. This time I save the qml cache of discover (attached here)
Created attachment 142668 [details] QML cache Discover
(In reply to Luca Beltrame from comment #10) > Either way, this is not a bug in Discover per se, so let's close this. I re-opened, added the qmlcache missing last time for you. Feel free to close again after you saw it.
Let's close this - this is a downstream issue. I currently don't have the link to the bug report, but the summary is that SOURCE_DATE_EPOCH is set based on the (human written) changelog only, and not updated on git builds. So the qmlcache appears to have a valid timestamp still. This needs to be fixed to take other sources into account as well.
