Um, I have encountered a strange crash.
I can't recreate the situation from scratch (yet) but I think I found the root that might be causing it.
The affected project was created in pre10 and today I moved it to pre12a but the behaviour is basically the same in both builds.
The project opens fine but when I try to open other project, create a new one or just delete some of the first few tracks (they are grouped), Reaper crashes.
After some experiments I noticed that I could fix it by deleting tracks 4 and 5 and saving the project again.
These two tracks include volume envelope with AI and they don't look the way I saved them yesterday. When I delete the first envelope point at 0:00, save and reopen the project, the point is back.
I suspect it creates some garbage in memory that (in some situations) causes the crash.
