Seems it's different with #bug 15588, From the above backtrace, it fail due to update userdb table, after #bug 15588 fixed, this can only happen if compiling with "--disable-userdb-cache" because it still try to update userdb hash table, this is not necessary because userdb cache disabled by user.

So here is a patch to fix it.
