Open attached file and find that the slide is missing some spaces between words ("Cпомощьюснифферарассмотрите").
Confirmed using 22.214.171.124.alpha0+ Build ID: cc2a405915e82c4b332dd25457f76704dc536d7f TinderBox: Win-x86@39, Branch:master, Time: 2013-10-15_15:51:52. Opens fine with 4.1.2.
In fact I saw this bug more than a month ago, but forgot to report. So we have a second test case: It's attachment 76439 [details] from bug 62260. There is also a screenshot of master build from 2013-09-01: attachment 85007 [details].
BTW PowerPoint 2010 SP2 reports that the file is corrupted, but I don't think it's related to this bug.
Still an issue with libreoffice-4-2 build (Build ID: f9171206e80b1ff3e3917e2f448ff2b2a43a0b2e), but fixed in master build (Build ID: 4c539fac018dfd44cd8db52161a8cb930c627da7).
