error uploading maven2 pom.xml while queue

with 1.2 I had the same problem even if build queue was empty
with 1.2.2 with queue empty works
with 1.2.2 uploading a pom.xml while other projects in build queue throws the following exception:

grants and owner of /opt/egovapps/apache-tomcat-5.5.27/work/Catalina/localhost/continuum/ are correct
