image with layer

Here is gif picture. When I open it in Gimp I see: Size of whole image 580 × 387 pixels. Size of layer 575 x 227 pixels. When I insert it in office it output on screen, it outputs only layer, but not whole image. HTML document becomes corrupt.
I tried it on Linux 64. Mozilla outputs whole image.

Comment 6 Thomas Arnhold 2013-05-01 02:42:05 UTC
I can't see any problem with master (didn't try 4.0).
Comment 7 sasha.libreoffice 2013-05-02 08:37:44 UTC
On second screenshot I see that problem is still reproducible. Picture ends exactly beneath frames of text. But should be empty space beneath of frames. And hight of picture should be almost 2 times bigger.

PS: this picture is generated by msWord by saving document as HTML. Pictures with this problem may be potentially very popular. And therefore problems is important.

What is interesting: copy-pasting this picture from Firefox to LibreDraw pastes it with correct size, but with black background (because pastes as JPEG)
Comment 8 Thomas Arnhold 2013-05-02 16:39:41 UTC
Ah ok, didn't see that it's bigger in height.
Comment 9 Julien Nabet 2013-11-15 23:48:22 UTC
On pc Debian x86-64 with master sources updated today, I reproduce the problem.

Michael: do you know who may help here? (eg by giving some code pointers?)

Many testers confirmed the issue, but I don't see it. 
I see that size in MSO is different, with some empty placeholder, but not in IrfanView. It says Original size: 575 x 227.
Image looks OK in LO.
I'll close this one. 
If someone objects, please explain and attach comparison screenshot.
