Now what?!? This should make no difference at all? Probably a shell bug.
However, that "export VAR=stuff" syntax is not compatible with early POSIX standards. In those early times, "export" was there to export already declared environment variables, i.e. "VAR=stuff; export VAR". But this can't be the bug in this case, I think. Then I don't know why the quotes are necessary. But if this really fixed the bug in question, let's be happy and blame the shell.
