example WMF picture

Problem description: 
When you drag & drop attached WMF picture into Writer/Impress or Draw then it can take up to 40 seconds of 100% CPU load before the picture is shown.
When the document is saved and re-opened the time it takes to open it directly proportional to the number of WMF pictures used: ie with 5 example WMF pictures it will take 5 time as long (with 100% cpu load) as with one picture.

Steps to reproduce:
1. open new drawing or Text document or Presentation
2. drag & drop example WMF file into document
3. Watch high CPU load for long time with Task Manager.

Current behavior:
Adding WMF picture to document or opening document with WMF picture in it takes a very long time. LibreOffice appears to be locked up for that duration.

Expected behavior:
Expect to show the WMF picture immediately. Powerpoint shows presentation with multiple WMF pictures in it within seconds.

Comment 4 cedrcaba 2012-12-17 19:40:06 UTC
I can confirm this bug on LibreOffice 4.0.0.0 beta1 and with this another WMF picture.
Note that Apache OpenOffice 3.4 and OOO 3.3 can open these files normally, albeit some graphicals errors.
Comment 5 Marco 2013-01-21 13:47:03 UTC
I can confirm this bug on platform LO 4 RC1, Version 4.0.0.1 (Build ID: 527dba6f6e0cfbbc71bd6e7b88a52699bb48799)

See also bug 45820, is this a similar issue?
Comment 6 Marco 2013-08-05 14:29:42 UTC
This bug is still present on LibreOffice Version: 4.1.0.4 Build ID: 89ea49ddacd9aa532507cbf852f2bb22b1ace28. It takes about 40 seconds to open the attached example WMF file.

Note that Apache OpenOffice 4.0 opens this WMF file normally within a reasonable time, about 1 second.

Callgrind analysis showed that it is the same as bug 45820.
