Newly regenerated workspace.xml ignores my sourceForlder specifications

Hi.

I have the following directory structure specified in my IML:

    <content url="file://$MODULE_DIR$">      <sourceFolder url="file://$MODULE_DIR$/src" isTestSource="false" />      <sourceFolder url="file://$MODULE_DIR$/test" isTestSource="true" />    </content>

It all works fine, but every time I make a clean (without .idea/workspace.xml) source tree checkout from my svn,

those sourceFolder declarations are getting IGNORED and the new workspace.xml contains only the default specifications (src/main/java, src/test/java etc),

so I have to manually reset them back to make everything (tests, to be specific) working again

Does anyone have any idea on how to fix this issue in my IDEA 13.1 CE?

Thanks in advance!
