6669,Debian Lenny guest VM crashs when copying large files from a USB disk,enry,,"I use a Windows Vista 32bit host and a VM guest (Lenny 5.0 Debian stable). 

If I access a 8Gb USB pen drive (fat32) or USB big disk (ext3 formatted) (previous registered in the Virtualbox GUI) containing large files (between 2.5 and 7 Mbytes) traying for example to do a copy to my disk (cp -v /media/usbdisk/myfile $HOME) the virtual machine crashs immediately (I can move the mouse but no more action is allowed).  

I have this problem with:

debian lenny guest (virtualbox 3.1.6)  Always crash

debian lenny guest (virtualbox 3.1.8)  Always crash

Ubuntu 10.04 guest (virtualbox 3.1.6)  Problems only if stressing the system with multiple copies (cp -v /media/usbdisk/myfile.* $HOME)

Ubuntu 10.04  guest (virtualbox 3.1.8   No problem. No crash. Copy is fast and  reliable. 

How to reproduce the problem: Insert for example a kingston 8Gb pendrive with 
some directories containing large files (for example big .jpg photos > 3 Mbytes
and debian VM crashs just when the disk is mounted automatically or at the first 
access.
