Problematic EMF

The attached EMF crashes LO on opening.
More specifically: the crash occurs AFTER open on any UI interaction: mouse movement over any toolbar, or command invocation (say, Ctrl+Shift+S).

Tested under Win7x64
Already present on: LO
Still present on:

Comment 1 Jean-Baptiste Faure 2014-10-07 04:55:31 UTC
No crash for me with Version:
Build ID: d4a1b5dc8aff03718625d03ad3ea77750069e196 built at home under Ubuntu 14.04 x86-64
My tests: 
1/ opening the file itself: it opens in Draw without problem
2/ inserting the image in a new text document: no problem in Writer and Impress.

That said LO freezed when I double-clicked on the image once it was inserted in an empty presentation.

Best regards. JBF

Confirming regression, drawing of this EMF works correctly through the 4.2 builds up to

So, regression early in the 4.3 branch, need to bibisect against alpha0+ builds. Thus far none of the pre-alpha1 fare especially well with the EMF if inserted or opened including a 2014-04-09 TB 47 build Version:, ID 20fb1bfc72e626251b435bcff2339e1e425c7130

But, it was handled OK at 4.2 tag off from master, i.e. functions correctly with  initial version: build

1. Open or insert attached EMF file in Draw
2. One or two zoom steps, then it closes.  

On the 4.2 builds, able to resize the EMF image with clean redraw.

Unable to capture much of a log, and WinDbg is being troublesome at the moment.

As expected OK on the release,

Bibisect results from Windows installers of on hand--these could probably be refined down further on a Linux


So, ~150 commits between 2014-01-15 and 2014-01-17

When I get a moment, I'll see what I can do.
Comment 5 V Stuart Foote 2014-10-12 05:51:17 UTC
A good chance that complex SVG files are also similarly affected--at least on Windows builds--have yet to fully parse things out. But, getting some instability in working with large SVGs that are otherwise stable through out the 4.2.x builds, but go flaky early in builds.

Will work on it but for anyone interested, for an example take a look at handling of SVG attachment 76676 [details] from bug 62461, SVG similar in complexity to the problem EMF here.
Comment 6 Chris Sherlock 2014-10-13 23:20:23 UTC

1. Open .emf file in Draw
2. Zoomed to 150%
3. Zoomed to 200%

It literally closes. No core dump as far as I can see, no stack trace.

@Caolán, *,

Yes, very much better. Both the EMF and the SVG are much more responsive when manipulating. Draw, Writer and Impress are stable when resizing.  

Can actually have a document page with both the EMF and SVG images placed, the drawing and repaint is a little choppy (to be expected with this much vector detail to render, right?), but can reformat page and resize images.

@Mike K. would you please verify it is working correctly for you.

Thank you very much!

@Caolán, might be a good candidate to back port for 4.3.4 -- Stuart
Comment 11 Caolán McNamara 2014-10-28 13:37:17 UTC
I have it in 4.3, and are trying for 4.3.3 with https://gerrit.libreoffice.org/#/c/12088/
