Major - P3 Description
mongodump --dbpath prints query errors to standard out, but never actually handles them. The error document is saved in the .bson file for the collection (corrupting the dump), and the tool exits with an exit code of 0. Verified with 2.4.10, 2.6.1, 2.7.0.
Reproduce with:
rassi@laptop:~/work/mongo $ mongodump --dbpath /data/db -d test -c foo -q '{$invalid:1}'
