Report to https://bugs.kde.org/

I am new to this, having not submitted crash reports before - my apologies if I am too verbose, or lacking in detail!

You might want to consider if this was caused by a Qt bug that was resolved fixed in 5.8, as described in Bug 361895, Comment 1.

Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.

 I cannot confirm whether this matter has been addressed or resolved - it was reported by me more than five years ago! It is now some time since I have used K3b for DVD burning and Mint has now ceased using the KDE system.
  

  
I am now using Mint “Yuliana” release 20, with the “cinnamon” Gnome UI, so it is impossible for me to run like-for-like testing or to try and replicate the issue.
  

  
My apologies,
  
D. Nelson-Wills.
