Registry backup - crash

Running version 2.1.117500.10. When I try to run a registry backup the application crashes. Windows reports the following error. Windows 7 64 bit.

Problem signature:
Problem Event Name: APPCRASH
Application Name: CBU.exe
Application Version: 1.0.0.1
Application Timestamp: 4aeaa369
Fault Module Name: StackHash_9d0c
Fault Module Version: 6.1.7600.16385
Fault Module Timestamp: 4a5be02b
Exception Code: c0000374
Exception Offset: 00000000000c6cd2

I can confirm the same problem, on the same OS, but using CB 2.2. The fault exception and offset are identical in all other respects.

The crash log states:

Please advise the fix, or if more details are required.
Right now, this is a showstopper.
