Description Derek Nelson-Wills 2015-03-21 13:54:08 UTC 
I was burning a large quantity of small .avi files from an SDHC card to a DVD-RW for editing in the future. When the process was approximately 3/4 complete, K3b crashed without warning.

Reproducible: Didn't try

Comment 2 Derek Nelson-Wills 2015-03-21 13:57:50 UTC 
I am new to this, having not submitted crash reports before - my apologies if I am too verbose, or lacking in detail!
Comment 3 Denis Kurz 2018-01-31 16:05:40 UTC 
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.
Comment 4 Justin Zobel 2020-12-17 05:33:46 UTC 
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.

No problem, Derek. Let's assume it will be reported again if the crash is still happening. Thanks for the feedback!
