[Bug 48962] cd writing fails from flight-7 installation

[mouhmouh]

Public bug reported:

I have a Plextor cd/dvd writer and I'm having problems writing cd's with
it. DVD writing seems to work fine. The following is the output from
k3b, but cd-writing also fails e.g. when trying to write an .iso file
using "right-click->Write to disk"...
