Summary: REG_MULTI_SZ RegistrySearch causes errors during MSI install

Initial Comment:
When a RegistrySearch element is reading a REG_MULTI_SZ, the resulting MSI 
fails to install to the location specified during feature customization, and 
will not uninstall via the Remove button.

For instance, if the registry contains the key:
HKLM\Software\TestWix\MyMultiString with values "Test1" and "Test2", the search

<RegistrySearch Id="mymulti" Root="HKLM" Key="SOFTWARE\TestWix" 
Name="MyMultiString" Type="raw" /> 

will cause the installer to exhibit the problems mentioned above.

Attached is a zip file with a sample project that demonstrates these problems.  
Changing the registry search to look at a REG_SZ key instead causes the 
problems to disappear.  

This was tested using version 3.0.2712.0.

There is definitely a weirdness going on. The good news is that it affects
only the UI; using 'msiexec /x' still removes the product. The neutral news
is that a RegistrySearch for a REG_MULTI_SZ isn't very useful; see the
RegLocator table doc:

REG_MULTI_SZ Null. The installer sets the property to a value beginning
with a null and ending with a null.

I'll keep the bug open to keep thinking about it but at first glance, I
can't think of a way the UI can change what MSI does.

I'm attaching a verbose log during an attempted uninstall via the remove
button.
File Added: uninstall.log

Can you attach a verbose log? Much easier to diagnose problems that way.
