Rtabmap processing dying with DB error

[asabet]

I'm getting this error when running rtabmap:

DBDriverSqlite3.cpp:5007::stepNode() Condition (rc == SQLITE_DONE) not met! [DB error (0.17.3): UNIQUE constraint failed: Node.label]

What could be going wrong?

Labels should be unique. Did you try to add a label already existing in the map (though you should have only an warning, not a fatal error if so)? Were you starting from a clean database or a previous one?
