Rearranger 4.0.2 exception

I don't know, when exactly this happened, just saw the flashing icon in
the status bar:


adjustSpacing: illegal syntax (mismatched braces); PsiElement for brace
is null
java.lang.RuntimeException: adjustSpacing: illegal syntax (mismatched
braces); PsiElement for brace is null
