Submitting a bug with K3b (2.0.2). Adding audio files by dragging and dropping them into project box. Segment faults.  Trying to burn some audio files onto a cd for family for xmas. Crashes every-time. They were .mp3 tracks.

Also, k3b sometimes crashes when right clicking on a directory to add audio files that way, also in the dialog box to "add to project" within K3b.  Hope that helps. 

I downloaded all of the backtrace tools to generate a full report. That backtrace tool is not working well connecting to the internet. Same username and password that works at the above link gives me an error that it is the incorrect one with the on-board backtrace tools and debugging symbols it downloaded onto my distro. 

Hope that helps. There were some bugs listed that could of been duplicates, someone had the same issue with wav files. 

Yeah, it scans the files in really fast and hangs up and crashes on my system and distro. Using Kubuntu 12.04.5 x64 bit.  Forgetting to pull the cover art out or other non relevant files trips up that analyzing engine within K3b too if they are in the same directory as the audio files.  That workaround keeps this bug from crashing K3b.

We don't accept bugs against "Application: k3b (2.0.2)".
