Crash with Impress, when creating an empty document including transitions.
IMPORTANT : the timing is important.
Issue verified with upstream DEV300, on Linux, Mac OS X and Windows
How to reproduce :
1) From the start center, choose create an Impress document
2) Empty presentation (same issue with templates)
3) click on Next
4) click on Next
5) Effet : choose Wheel Clockwise 4 Spokes (but other should cause the crash
too)
6) Once the effect is choosen, the preview starts : wait for the end of the
preview (the preview is
enabled by defaut)
7) Just after the preview ends, click on "Create" EXACTLY between the moment
the preview is finished,
and before the background becomes grey
-> crash, fully repeatable
Expected : a new Impress document with the previous transitions between slides.
Verified on Linux, Mac (Tiger Intel) and Windows.
After tracing with Thomas (alias twarz), we finally think the cause of the
crash is :
PresentationEnd msg comes by timer, and sd continues to work on an already-dead
window.
The log : I catched the following trace (vcl, slideshow, sd, sfx2 libs have
symbols included):
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000129

IMPORTANT:
The cause of the crash was hidden, because several null pointers, and the to be
able to retrieve the
