Brasero crashes when trying to open another instance of it while creating an iso file from a cd/dvd

[António PT]

Binary package hint: brasero

How to replicate: Open Brasero. Put a CD/DVD (dvd in my case) in the drive and start making an iso file from it. Then try to open another instance of Brasero. It crashes with segfault.
