[Bug 998389] [NEW] Brasero crashes on clicking the close window control while burning

[Jonas Schwabe]

Public bug reported:

I am sorry I can't attach an apport bug report as apport simply does something wired while reporting this (simply disappears but does not crash). I will look into this, too.
I will therefore attach valgrind output and the unformated crash file. But I think this will likely be reproducible for everyone as it does not only happen while burning but also while creating iso files.
Steps to do:
Create a new data disc with brasero, if you want to try this with iso files put some big files onto the disc as you need a few seconds to reproduce the bug.
Start the burning/writing process and simply click on the close button (X) in the window control.
Program crashes and if you really burn something the disc braseero was burning won't stop spinning. I had to use "cdrecord -abort" to eject it as eject just shows: 
eject: Kann nicht auswerfen! Letzter Fehler: Unpassender IOCTL (I/O-Control) für das Gerät
(eject: Eject failed! Last error: Wrong IOCTL for this device)

What I was expecting:
Either a confirmation to cancel the burn process or a simple minimization to the notification area.


Valgrind output attached.
