Description:
In some old presentations that I have on my disk, animations and transitions are handled incorrectly in the current LO. This happens only for some presentations, and only for some slides in them; for others everything is all right. The file I used to demonstrate the issue is probably the most severe case I found.
These presentations all opened correctly in OpenOffice 3.2.

Steps to Reproduce:
1. Open the sample file http://rafa.eu.org/share/lo_issue/murach.odp
2. Start the slideshow.


Actual Results:
1. On the first slide, after clicking the mouse, the text "Geography" appears together with the map picture (this is correct).
2. After a short delay, horizontal and vertical dimensional arrows appear, but they don't seem to be animated (this is only partially correct, because they should be animated).
3. Immediately after this, Impress advances to the next slide (this is completely incorrect, there is a lot more to display on this slide).
The behaviour is shown on the video: http://rafa.eu.org/share/lo_issue/transition.new.ogv

Expected Results:
1. On the first slide, after clicking the mouse, the text "Geography" should appear together with the map picture.
2. After a short delay (1 second), horizontal and vertical arrows should appear. Horizontal arrow should be animated from right, vertical one from top.
3. After a mouse click, a block of text "area: 889 km2" should be animated from the left, followed by several more blocks of text every 2 seconds.
4. After last block of text is displayed, Impress should wait for mouse click before advancing to the next slide.
The correct behaviour (recorded using OpenOffice 3.2) is shown on the video: http://rafa.eu.org/share/lo_issue/transition.old.ogv


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
The behaviour is unpredictable when I try to edit the animations/transitions. For example, when I change the text block "area: 889 km2" to be displayed after delay instead of after a mouse click, the behaviour is completely different:
1. At the beginning of the slide show, there is no wait for mouse click, the text "Geography" with the map picture appears right away.
2. After a short delay, horizontal and vertical dimensional arrows appear (without animation). This is the same as in the initial result.
3. Immediately after this, all  blocks of text appear at once (without any delays or animations) and Impress waits for mouse click before advancing to the next slide.
