I run the following command as a build step manually (I also tried using the plugin to run valgrind with no effect on the output)

valgrind --tool=memcheck --leak-check=full --show-reachable=yes --undef-value-errors=yes --track-origins=yes --child-silent-after-fork=no --trace-children=no --error-exitcode=1 --xml=yes --xml-file=./my_report.valgrind ./my_executable;

my_report.valgrind is generated and it contains couple of errors. But the publisher doesn't seem to pick that up. And when I click on the Valgrind Result link in the my project's home page it tells me no errors

I've set the Report Pattern field to the expected xml name (i.e. wimatek_ps.valgrind).

Am I doing something wrong?

Below are the versions I'm using
Jenkins version 1.567
Valgrind plug-in version 0.20
Valgrind version valgrind-3.10.0.SVN
