I opened Excell 2000 spreadsheet in opencalc and started converting it to pdf. 
I have chosen printer quality. I got the message in gui "Unrecoverable errors
ocured.  All changed documents will be saved and can be restored" (something
close to that anyway)

Here is the trace

[alexl@zmey OpenOffice.org1.1]$ ./soffice
