Hi there,
I'm also seeing this segfault.
I should add that I'm observing this when I'm using the mouse to click
through slides - if I don't click and only use the keyboard things seem
to work. This is different from what the original reporter saw.
After installing all the debug symbols required, I see the following gdb
backtrace and valgrind output:
