Version:           0.12.15 (using KDE KDE 3.5.3)
Installed from:    Debian testing/unstable Packages
OS:                Linux

alecs1 <nuorama@gmail.com> reported the following bug on the Debian bug tracker (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=374975).  I have asked him for more details as to what kind of burner he is using and I will add a note to this bug once he has responded.  I just wanted to let you know about this potential right away in case you want to fix it before 0.12.16 is out.

Here's his post:

K3b crashes when verifying the written data (the data seems to be correctly
written). Some time ago it randomly(?) failed with "file not found to test
the data on cd-s which had also udf extensions.

The debug from the kde crah handler:
