PsiInvalidElementAccessException because different providers

Can anyone explain why this exception occurs?

com.intellij.diagnostic.PluginException: Element: class com.jetbrains.python.psi.impl.PyReferenceExpressionImpl #Python  because: different providers: com.intellij.psi.DummyHolderViewProvider{vFile=LightVirtualFile: /DummyHolder, content=VirtualFileContent{size=0}, eventSystemEnabled=false}(16a6790e); com.intellij.psi.SingleRootFileViewProvider{vFile=LightVirtualFile: /DummyHolder, content=VirtualFileContent{size=0}, eventSystemEnabled=true}(49b15b25)
