           Summary: Some (probably malformed) RTF files crash LibO 3.4,

          Platform: x86 (IA32)

            Status: NEW
          Severity: critical
          Priority: medium

An example of such a file

A bit of context : The french ministry of economics (Bercy, for the french of
us) provides some useful forms to local administrations (towns, counties, and
the such). Those documents are provided in RTF format, and they've often been
problematic : random OOo (in the old times) crashes, formatting issues, etc.

Still, the problems seemed to become scarce over the time, and I had a lot less
issues with LibO 3.3. Sadly, LibO 3.4 might have included a regression : the
very same file that somehow worked on 3.3 freezes 3.4 (blank screen right
before the "File import" progress bar completes, 50% CPU usage forever)

It's easy to reproduce, at least on a Windows machine (yet to test on other
OSes) : run LibreOffice 3.4, open the given file, and enjoy. The very same
process on 3.3 gives us rather quickly a readable content (progress bar goes
unnoticed).
