Contacts api not working when using signed AuthSub token

Name of API affected:
Contacts Data API for Java, AuthSub

Issue summary:
Contact query fails when using signed authsub session token and using 
query.setStringCustomParameter("group", group) query.
Works fine with unsigned session token.
Works fine when removing custom parameter from query (but keeping other 
filters like maxResults etc.)

Steps to reproduce issue:
1. Create an app on appengine
2. Register app with https://www.google.com/accounts/ManageDomains
3. Verify your page and upload a certificate
4. Create valid authsub session token using keystore
5. Create a contact query using custom string parameter (see above)

Expected output:
What do you expect to see after performing the above steps?
Same query result as when using unsigned token

Actual results:
What do you actually see after performing the above steps?

I'll get an exception:

Notes:
This is a simplified example how to reproduce the bug:

PrivateKey key = AuthSubUtil.getPrivateKeyFromKeystore("keystore.jks", 
"passwd", "MyApp", "passwd");
contactService.setAuthSubToken(token, key);
URL feedUrl = new URL(CONTACTS_SCOPE + "contacts/" + email + "/full");
Query myQuery = new Query(feedUrl);
myQuery.setMaxResults(5);
myQuery.setStartIndex(1);
myQuery.setStringCustomParameter("group", createdGroupId);                  
ContactFeed resultFeed = contactService.query(myQuery, ContactFeed.class);
