Created attachment 105832 [details]
crashing presentation

For me not reproducible with LO 4.3.1.2 (Win 8.1).
Therefore, this issue maybe hasn't occurred in earlier LO releases? 

Steps done:
1. Opened the attached presentation
2. Went to VIEW -> TOOLBARS and selected FORM CONTROLS
3. Switched ON the DESIGN MODE (icon at the top right)
4. Used Page Down keys to scroll through the presenation

I do not reproduce the crash with following versions build at home under Ubuntu 14.04 x86-64 :
- Version: 4.3.2.0.0+ Build ID: 10817252c56f48b0026158fc37a55005098a9d78
- Version: 4.4.0.0.alpha0+ Build ID: dbc24b1ff71a8da7e23e9c1657492fb3c8a66de8

To be sure: what do you mean by "design mode"? I understood that as edit mode.

Best regards. JBF

Hi

Sorry for not being clear. I mean the 'Normal' mode.
And my Version: 4.4.0.0.alpha0+
Build ID: 1298c1d13572c6fbfbabb813b2d6843368c6df1f
Working on Ubuntu Linux 32 bits

It also crashes with a clean user profile.

Hmmm, your build is old (395 commits older than mine), I suggest you to try again with a current daily build.

Best regards. JBF

Following the instructions provided, I have made a segfault with
PC=0x0; frame 1 of the backtrace is in function
GraphicObject::ImplAutoSwapOutHdl(void*).  

I notice in at least one version, if I start by typing <End> to
display Slide 4, there is no crash, not even when I type <Home> and
then successive <Page Down> to leave and return to Slide 4.  Maybe
this says something about how the segfault happens.


The crash appears to have been introduced and removed from master
within the range covered by the daily dbgutil bibisect repo.
Specifically, it first appears in 369f344... 2014-08-10 and it is
first gone in 8c0ffaa... 2014-09-01.

So, this bug report is obviously headed for FESOLVED WORKSFORME.  But
I wonder if there may be implications for other branches.  I shall
leave it for somebody with better git-foo than mine to resolve the
report.


For completeness, as I worked from the oldest version in the repo to
find the introduction of the crash, I see `git bisect bad` says:
