I've been doing a little more testing. I find the following transitions cause 
an immediate crash on application to a presentation under construction:

Fade Smoothly
Fade to Black
Flipping Tiles
Outside turning cube
Fall
Turn around
Iris
Turn down
Rochade

In general, I only tested one of each group of transitions. I assumed if (e.g.) 
Wipe Down worked, then probably all  the other Wipe directions would be stable 
also.
(OO 4.1 on Xubuntu 14.04)

Other than Fade Smoothly, I cannot comment on stability when they are used in a 
Slide Show of an existing presentation. My expectation would be that such slide 
show might immediately crash. as happens when Fade Smoothly is used in an 
existing presentation.
