crashes without comment while trying to copy DVD to HDD

[LAZA]

the DVD works without problems and could be played painless.

i tried to copy this DVD to HDD - brasero crashes directly after pushing the button "make the image".
tried it again from command line and got the messages as you can see in the attachment.
