I just happened to have the doom classic music mod loaded when trying out Sigil with the `.ded` provided by Skyjake
. All golden... except when I activate the Baron wall mural at the end of the first map it crashes to destop (segmentation violation). While this problem is resolved rather easily by simply disabling the classic music mod (it's not used with Sigil anyway) I believe this is still a doomsday2 issue (at the minimum, a CTD indicates the need for better error handling in the specific case).
From the logs (attached), it looks as though doomsday attempts and fails to delete the existing vorbis buffer file, and then segfaults when it cant create a new one with the same name as it attempts to start the new level. Why this only shows up with the classic music mod loaded I'm not sure. It does not
happen with Skyjake's music remix mod loaded.
