This is pretty important. Without mongo, we cannot use iwhd at all, and lots of Aeolus depends on iwhd...
Hey Jim, I just tried this out on updated rawhide with mongodb-1.8.2-10, and I don't get the segfault. Granted, I didn't *do* very much with the mongo shell, but it didn't crash on me right away: [root@localhost ~]# mongo MongoDB shell version: 1.8.2 connecting to: test > show dbs admin (empty) local (empty) test (empty) > db.test.find(0 ... ) > db.test.find() > show collections > use local switched to db local > show collections > show users Can you try it out again on your setup and see if you still see the problem? Thanks, Chris Lalancette

The update from -9 to -10 solved the problem. Thanks for doing that. Now, iwhd's mongo-using tests all pass.
