Redmine

I'm getting this error when trying to browse the subversion repo:
"The entry or revision was not found in the repository."

As you can see in the log below, the whole request spends about 0.3sec, however if I try manually:
svn list --xml 'http://svn-repo:8080/svn.pi/nf-e/trunk//'@HEAD --username 'fernandos' --password 'svn-passwd'
the svn host spends at least 0.3sec but even more.

Since I don't have control over the svn repo, is there a way to make redmine wait the proper time until the svn-repo
response?
