Comment 11 for bug 734424

Hi,
Sorry for the delay, it was kind of hectic at work.
I also did not want to attach the sheet causing the problem, as it contains all my personal data.
I threw out my personal stuff, and the sheet still has the problem, so I'll attach it to the bug report,
along with a new strace.log

As you see on the tcpdump output, the problem is dns related.
 here I start tcpdump and opened the sheet test4homesheet2011.ods from file/recent documents
marc@VASTEPC:~$ sudo tcpdump -nnl -i eth0 -s 1536 dst port 53
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 1536 bytes
