Be aware that the Debian (and thus Ubuntu) maintainers do mangle with the
standard Ruby distribution in non-trivial ways, so you might be their fault.

Although I cannot imagine why such a thing would happen, because their patches
usually concern packaging issues.

But it shouldn't hurt to file that as a bug report to them.
