Bug 243118

Application: k3b (1.91.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
K3b crash while passing (.cue + .flac) to mp3 (using lame):

The k3b coded to mp3 all the flac album, but never stoped of showing the progress. It stayed at almost 100% of completion all time, using all cpu cycles available, and never stop running.

The crash can be reproduced every time.

 -- Backtrace:
Application: K3b (k3b), signal: Bus error
