abrt oops when copying file to VirtualBox shared folder => Fixed in SVN

[unxguru]

I have VirtualBox 4.2.6 running on a Windows 7 x86_64 host with a Fedora 17 x86_64 guest. I have enable shared folders to the guest. When I copy a file to the shared folder ABRT reports a kernel oops. The copy completes and the file is in the folder on the Windows host, but the oops should not be happening.

In addition to extracting the stacktrace from the abrt log I have attached the a gzip'd tar file with the oops directory that abrt created and the /var/log/messages file as well as the vbox.log file for the VM.

This is the stacktrace:

The stacktrace didn't paste very well so here it is again.
