Comment 6 for bug 1935568

Yes I understood that, that's why I explained a bit about jack and that I never saw an apport activity or the problem with the dmesg dialog before just because of jackd.

So, I deleted the /var/crash stuff, and locked the screen and back in, as you suggested, but no problem appeared.

I could provoke a jack crash again by switching my sound device off while jack was running.
I get crash reports in /var/crash but no hanging dmesg dialog as described in the original report.
