plugins_test failing

Hi,

I've run the RTT tests on my machine: a Intel Atom based mini-ITX equipped
with Ubuntu 10.04.1 LTS, kernel 2.6.34 and xenomai 2.5.4. All tests run fine,
except for the plugins_test:

sudo ctest
<snip>
32/33 Test #32: typekit_test ..................... Passed 0.21 sec
Start 33: plugins_test
33/33 Test #33: plugins_test .....................***Failed 0.23 sec

97% tests passed, 1 tests failed out of 33

Total Test time (real) = 43.98 sec

The following tests FAILED:

*** 6 failures detected in test suite "Master Test Suite"

I've got no idea why it is failing.
