Description Joel Madero 2014-05-29 03:32:04 UTC
Steps to Reproduce:

Open attachment 98599 [details] in LibreOffice - 4.3 beta1

The document is 11 pages but are merged into a single page and CPU spikes

Here it's tricky as the bibisect only shows the regression but the file has an additional bug associated with it (bug 78730) which makes it so the document shows 10 pages instead of 11 - ideally the file opens perfectly, but worse case it should at least open like it did prior to this regression

Confirmed. It was actually bug 78370.

current libreoffice-4-2 and libreoffice-4-3 branch 1-page and looping and master don't loop, on 11 pages

    RTF import: fix spurious page breaks at doc end (related: rhbz#1065629)


ok this one fixed it on master:

commit 75fc9e669f209472ec6a282848166d96d02d84d9

    fdo#78904 : LO hangs while saving the document.
Comment 5 Michael Stahl (CIB) 2014-07-30 16:05:33 UTC
fixed on libreoffice-4-3 branch by commit

...unfortunately this backport is apparently not enough to fix it for 4.2...
Comment 6 Michael Stahl (CIB) 2014-08-01 10:29:24 UTC
these commits are needed to fix it for 4.2:

    fdo#70578: writerfilter RTF import: by default style is para style 0

    writerfilter: NS_rtf::LN_SGC -> NS_ooxml::LN_CT_Style_type

commit 1be0a3fa9ebb22b607c54b47739d4467acfed259

AuthorDate: Tue Jun 17 18:40:04 2014 +0200

    n#825305: writerfilter RTF import: override style properties like Word

... argh ... the last one is rather risky and i don't want to backport it
for 4.2.7...

what makes the difference between looping and properly paginated
document is the default paragraph style containing 10.5 pt Calibri font
{ \fs21\f37 Normal;}

meh.... i'd say this document is a pathological case, and the various
import filter changes just trigger a pre-existing bug in Writer's
horrendous layout code; there won't be many documents affected
in this way by commit e3f254ab8211fbab7541cde2100a35c875b0c240
and so fixing this in 4.2 is not worth it;
resolving fixed in 4.3 and master.
