A tomboy user experienced an error after a system crash.  After the crash some
files in addin-db-001/addin-dir-data were truncated to zero bytes.  
Mono.Addins.Serialization.BinaryXmlReader will go into a recursive loop until a
StackOverflow occurs when reading a zero byte file.


Reproducible: Always

Steps to Reproduce:
1. Truncate to zero bytes the files in (ex
2. Start a project using Mono.Addins (ex Tomboy)

Actual Results:  
A stackoverflow exception.  See the tomboy bug for actual stack traces.

Expected Results:  
Mono.Addins should recreate its addin databases if it is corrupted.

Deleting the addin-db-001 directory workes around the problem.
