Force close due to Logger (calendar client)

Version of google-api-java-client (e.g. 1.5.0-beta)?
1.10.3

Java environment (e.g. Java 6, Android 2.3, App Engine)?
Android, all

Describe the problem.
Force Close
The chosen LogFactory implementation does not extend LogFactory. Please check 
your configuration. (Caused by java.lang.ClassCastException: The application 
has specified that a custom LogFactory implementation should be used but Class 
'org.apache.commons.logging.impl.LogFactoryImpl' cannot be converted to 
'a.a.a.a.c'. Please check the custom implementation. Help can be found 
@http://commons.apache.org/logging/troubleshooting.html.)

Not a consistent bug, can't even recreate it myself. Why does this issue come 
up at runtime and not during obf?

How would you expect it to be fixed?
A ProGuard setting that would avoid this.
