Looked at dev.22 and we were handling this error case correctly there.
No, we're handling this error case correctly now.
Either you forgot to update your ntirpc, or there's a serious error in
ntirpc. NULL should never be returned here.
Based on the backtrace, ntirpc is updated (ie, the line numbers all line
up). There must be some way to return NULL here that we missed.
