If you'd like to add additional backtrace events to a bug, a better way is to turn on Automatic reporting when Dr Konqi launches. Opening and closing duplicate bugs for the same crash only clutters up Bugzilla.
Comment 4 Roke Julian Lockhart Beedell 2025-08-02 00:03:07 UTC 
(In reply to TraceyC from comment #3)

I can't access Sentry events, though, which means I can get kinda confused when I see multiple ABRT reports in RHBZ that don't correspond 1:1 to KDE BZ bugs. I thought it best to do this than accidentally repeat information that's already in sentry. I try not to report them unless I've reason to believe they differ, but perhaps ABRT considering them different isn't sufficient? Apologies regardless.
