I've been trying to burn data CD:s. During burning this message is written to the command prompt where brasero was started: brasero (libisofs)MISHAP : Image write cancelled However, brasero continues to burn the CD and creates an unusable disc (or a 2 MB ISO file), no error message in brasero window: BraseroBurn: (at burn-libisofs.c:672) BraseroLibisofs Found parent brasero (libisofs)DEBUG : Creating low level ECMA-119 tree... brasero (libisofs)DEBUG : Matching hardlinks... brasero (libisofs)DEBUG : Sorting the low level tree... brasero (libisofs)DEBUG : Mangling names... brasero (libisofs)DEBUG : Creating low level Joliet tree... brasero (libisofs)DEBUG : Sorting the Joliet tree... brasero (libisofs)DEBUG : Mangling Joliet names... brasero (libisofs)DEBUG : Computing position of dir structure brasero (libisofs)DEBUG : Computing length of pathlist brasero (libisofs)DEBUG : Computing position of Joliet dir structure brasero (libisofs)DEBUG : Computing length of Joliet pathlist BraseroBurn: (at burn-job.c:1925) BraseroLibisofs called brasero_job_set_output_size_for_current_track brasero (libisofs)DEBUG : Starting image writing...
