Calc opens the file perfectly, but Writer hangs in an infinite loop. Attaching
a debugger and backtracing a few times, I saw it's often running code in this
function from main/sw/source/core/doc/docbm.cxx:

---snip---
::rtl::OUString MarkManager::getUniqueMarkName(const ::rtl::OUString& rName)
const
{
    OSL_ENSURE(rName.getLength(),
        "<MarkManager::getUniqueMarkName(..)> - a name should be proposed");
    if ( findMark(rName) == getAllMarksEnd() )
    {
        return rName;
    }

    ::rtl::OUStringBuffer sBuf;
    ::rtl::OUString sTmp;
    for(sal_Int32 nCnt = 1; nCnt < SAL_MAX_INT32; nCnt++)
    {
        sTmp = sBuf.append(rName).append(nCnt).makeStringAndClear();
        if ( findMark(sTmp) == getAllMarksEnd() )
        {
            break;
        }
    }
    return sTmp;
}
---snip---

That "for" loop has a limit of SAL_MAX_INT32 (over 2 billion), and the
condition that would cause it to "break" seems to never be met, thus it just
spins there.

Putting a breakpoint on that "if" statement within the "for" loop and printing
the contents of "sTmp" on each loop run, I get:

__tmpTD1547
__tmpTD1548
__tmpTD1549
...

and the "break" is never reached.
