A lock up is probably the result of some component crashing. So to debug this problem we will probably need to get some crash reports. Please do these (in the VM):
1. Apply the workaround from bug 994921.
2. Reproduce the problem, then look in /var/crash for crash files, and run: ubuntu-bug /var/crash/YOURFILE.crash
3. If everything goes well, 'ubuntu-bug' will create a new bug report each time you run it. So let us know here those new bug IDs.
Please don't try attaching crash files to existing bugs because we can't debug them that way. They must be uploaded using the 'ubuntu-bug' command.
