Description Mingzhe Wang 2013-09-10 08:15:16 UTC

Libreoffice crashes when I press F5.

It doesn't crash for newly created files, but it crashes on each ppt(x)s that I tried.

It hangs when I pressed F5, using a converted odp (from ppt).

Version: LibreOffice 4.1.1.2 410m0(Build:2)
Distro: Arch Linux
Kernel: Linux 3.10.10-1-ARCH #1 SMP PREEMPT Fri Aug 30 11:30:06 CEST 2013 x86_64 GNU/Linux

I found the real problem. It's not about file type, or something else. It's just the bug of transition effect.

For some effect, it works. But for some effect, it hangs or raises a segment fault.

The crashing transition effects:

Fade though black
Fade smoothly
Flipping tiles
Outside turning tube
Revolving cricles
From "Turning around" to the end of the list

I can confirm this bug on Ubuntu 13,04 with Libreoffice Version: 4.1.1.2
Build ID: 410m0(Build:2).

This is a killer bug for anyone who does a lot of presentations.

Libre Office Version: 4.1.1.2
Running in Manjaro Linux

Same thing happening to me.
Impress automatically crashes when applying many transitions.

As someone mention this is a principal feature for a presentation software, I'd say is a critical bug.

I rather suspect that this is a opengl driver crash. So...

a) can I get an actual backtrace of a crash, e.g. 
gdb /opt/libreoffice/program/soffice.bin
(gdb) run
...get it to crash and back in gdb do
(gdb) bt
and attach that here.

b) what your X driver, i.e. attach your /var/log/Xorg.0.log

I don't know whether it's the bug of LibreOffice or OpenGL, but it *does* work now.

Thank you very much for all the efforts you made!
