Upgraded DTPO crashes when I synchronize

Subject pretty much says it all. I upgraded to 1.5.1.
Told it to synrchonize some PDFs.
It indexed 50 new PDFS fine.
Then it set about to synchronizing something like 2500 documents.
Get’s up to around 60 and crashes.

In case of a crash please send the crash log (in your home folder > Library > Logs > CrashReporter) and possibly information from the Console (in Applications > Utilities) to support@devon-technologies.com and it will be delivered to the right person who can check it out.
