NUnit Parser stage does not report errors when parsing an invalid XML input

One of our unit tests prints out a NULL character (0x00) when failing.

The NULL character ends up in the message tag of the XML result file.

Bamboo seems to be silently ignoring the NUnit XML parse failure and the failing unit test result in this XML file is ignored (but not the successful ones that ran before). Any trace of this test just vanishes from the Bamboo build and the build is greenly marked as having passed.

In other words: one failing unit test, yet Bamboo says everything is fine.
