Short description of error
Joining a mesh to an existing mesh that is used as a boolean modifier causes a crash
Exact steps for others to reproduce the error
open the attached blender file. 2 meshes are selected. type ctrl-j to join them.
Sometimes it crashes immediately, sometimes I have to hit Tab twice, then it crashes.
When this initially happened, the crash.txt file contained the message:
CSG failed, exception /home/sources/blender-release/extern/carve/lib/intersect_face_division.cpp:578 "implement me"
but when I was able to reproduce it, that message was no longer in the crash.txt. I mention it just in case it provides a clue.
