Run svnadmin verify against the repository to ensure there are no machine-fixable errors.
Enable DEBUG logging of the Subversion plugin by editing the log4j.properties file (under $JIRA_INSTALL/atlassian-jira/WEB-INF/classes/) by adding the following entry to the file:

# Subversion Debug logging
log4j.category.com.atlassian.jira.plugin.ext.subversion = DEBUG, console, filelog
log4j.additivity.com.atlassian.jira.plugin.ext.subversion = falsethen restart JIRA to enable the change.
Cause
The Subversion repository is not providing data when the getLogEntriesByRepository method is run. Running svnadmin verify against the repository produces no errors or information (it considers the repository "clean and safe").
