There are some reftests that deliberately cause a plugin crash, resulting in the test suite harness flagging them as errors (if there happened to be at least one reftest failure in the test run). The reftest harness should be able to remove the minidumps if an individual test indicates that it will be crashing a plugin. (Bug 642175 handles the same thing for mochitests.)
