Software/OS onfiguration: 64-bit Windows 7 Home Premium running VirtualBox 4.1.0 with a Fedora 14 64-bit client os (kernel ) on an Intell i5 mobile platform (VirtualBox running Fedora with half of the (ht-) cores). 

Maybe some kernel network watchdog just has a tad too short timeout for (this particular) virtualization config (just quessing, though)..

How to reproduce
-----
1. Not sure either of the cause or reproducibility
2. Abrt has reported this crash now twice in a couple of days, so thought to send it in
3. Haven't noticed any effect on operation though (network error, network loss or any such)
