this bug is indicative of a pervasive problem in ardour: the missing session. tim suggested some time ago that we should do something akin to what emacs does when started without an explicit file: just have a default buffer sitting there. it would eliminate a huge class of bugs, and remove all the if (!session) code that is dotted all over the place. |

fixed in paul's code, november 4th 2003. another clear example of the problems caused by not having a default session. |
