What I did (steps to reproduce)

Just use xkeyval package, and try to use named argument that has round braces inside curly ones. It will be reported as <parameter text>, LatexTokenType.&, LatexTokenType.*, LatexTokenType.CLOSE_BRACE, LatexTokenType.CLOSE_BRACKET, LatexTokenType.COMMA, LatexTokenType.COMMAND_TOKEN, LatexTokenType.EQUALS, LatexTokenType.EXCLAMATION_MARK, LatexTokenType.NORMAL_TEXT_WORD, LatexTokenType.OPEN_BRACE, LatexTokenType.OPEN_BRACKET, LatexTokenType.PIPE or LatexTokenType.QUOTATION_MARK expected, got '(' error, while it should not.

Minimal example to reproduce the problem

\documentclass{article}
\usepackage{xkeyval}
\begin{document}
\anycommand{
  test = {Some thext with (Round Brackets)}
}
\end{document}

Expected behavior

No errors - this is perfectly valid code. I have no idea whether xkeyval is "truly" supported, but it seems to normally work, so breaking like that is surprising.
Interesting note: if (Round Brackets) is surrounded by additional curly braces, to form: test = {Some thext with {(Round Brackets)}}, error goes away.
