Thanks for the bug report. This is already fixed in my upstream version 8.38. I'm up to 8.40, for which I have received no bug reports and in which I have encountered no bugs myself since I released it two months ago. In addition to some bug fixes, there are some significant increases in functionality since 8.29, so my suggestion to the maintainer is to upgrade to 8.40. (It is also true that I've added some dependencies so this won't be entirely trivial.)
