I'm certainly no expert on this, but I'm trying to resolve some similar
issues with X11 apps on -current sparc64. My approach has been:
- Rebuild the app with debugging info (CFLAGS+="-g")
- Run the app and make sure I get a core dump
- Debug the app with gdb using the core dump just created 
  ("gdb app app.core" and then run/step/etc)
That will get you to the line of code that's causing the bus error.

In many cases they're caused by bugs (typically assumptions about the size
of longs).
