At least it happens randomly in my case. I've recompiled Xfburn following the instruction in the README file to get debbuging support. This is xfburn.output I've got when Xfburn crashed: Gdk:ERROR:/build/buildd-gtk+2.0_2.20.1-2-i386-TNeM25/gtk+2.0-2.20.1/gdk/gdkregion-generic.c:1108:miUnionNonO: assertion failed: (y1 < y2) xfburn.backtrace is blank. I was a adding a folder when it crashed. It also sometimes crashes when I press "Burn", but I have no output for that. On the other hand, it freezes when I add directories and remove them. This should not happen. Cheers, Marco
It's a really old bug, so I'm closing it. Please reopen if needed.
