I am using experiencing some problems with the SVN integration. Even as the credentials for the repository are saved in the svn config dir, quite often a dialog appears asking for credentials when updating the project or any other actions related to svn. This procedure needs to be repeated several times, even ticking the 'save credentials' checkbox seems to have no effect.
Some possibly related lines from idea.log:

Did anyone experience something similar?
