memcheck results for import/export

Hey,

as mentioned during the ESC call we have now results for a memcheck run
against 20k documents during import/export.

The logs can be found as zip at
http://dev-builds.libreoffice.org/crashtest/memcheck.zip . Note that you
still need to grep for a memcheck string as it contains all the log files
for all files. Some of the strings that I use and that work are "Invalid"
and "Conditional jump".

I hope that it helps fix some nasty memory problems.

Thanks already to Michael who fixed two problems that will not show up
anymore in the logs linked above.

Regards,
Markus
