I just had a funny bug i have to blog so that googlers can find it:

Eclipse 3.x using Subclipse on windows (which works fine)

Error:
Error validating location: "org.tigris.subversion.javahl.ClientException: RA layer request failed
svn: profind request failed on /repos/foafme

Server certificate cerification failed:
issuer is not trusted (https://foafme.opendfki.de)

keep location anyway?

Problem: our crew does not sign their certificates correctly (or) and the foafme.opendfki.de thing has a SSL certificate which is not correctly signed (or whatever)

I click on "add repository" and it says "the certificate is wrong" and i say "ok" but it still doesn't work

Solution: Take another SVN client (commandline or tortoise svn) and connect to the server, press "OK" there when the certificate question comes. Then it works in eclipse also. problem solved.
