There's a OOo bug <a href="http://www.openoffice.org/issues/show_bug.cgi?id=84159">http://www.openoffice.org/issues/show_bug.cgi?id=84159</a> which describes a crash happening if document has too much formatting. This also applies to LO. It usually happens at closing the document but can also happen at some other (almost) random times. There's also a fix ready for that bug in OOo and I was wandering if it may get into LO release. Thanks Andriy
