Description of problem:
I tried to get bugs in status other than CLOSED. This should be around 40k bugs. Despite the fact that limit for XMLRPC is set to 100k bugs my query fails with 500 Internal Server Error

Version-Release number of selected component (if applicable):
3.2

How reproducible:
Always

Steps to Reproduce:
1. Run query with following params
query = {
            'column_list': ['bug_id', 'changeddate', 'bug_status'],
            'bug_status': ['NEW','ASSIGNED','MODIFIED', 'ON_DEV', 'ON_QA', 'VERIFIED', 'FAILS_QA', 'RELEASE_PENDING', 'POST']
}
             
            
Additional info:
If I limit the query to return just 'NEW','ASSIGNED' it works. (roughly 23k bugs)

I met similar behaviour while requesting full bugs in multicall. So the problem might be in some size limit for XMLRPC response.
