[Henrik Skupin [:whimboo][⌚️UTC+1]]

One of those cases when it was not possible to read the minidump file. Gabriele, if you have a minute maybe it's something we could use for figuring out the reason? If not this should be most likely a dupe of a meta bug.

Here is the minidump file:

Comment 3

[Gabriele Svelto [:gsvelto] (PTO)]

The minidump is empty so it was most likely not written out correctly in the first place. We've seen this happen in other bugs too though very infrequently. I still have no idea how this might be happening though.
