VM reset when using shared folders on 7.0.13-160260 and 7.0.97-160431

[boxer01]

Under the above-mentioned versions, VM reboots itself sometimes. Step to reproduce:

1. Wake up the host (don't think it's important, but that's what I did)
2. Share some folders from the host o the VM
3. Try to download something with Firefox directly to the shared folder.

Download starts, but the host is reset couple of seconds later.

A put here what I see in my log file.

This probably should be closed because I didn't have such issues for a while.
