Thank you for the report.  Although I cannot be sure what exactly
happened to you, I have checked the code and fixed several places where
such TTLs could be created.  I added a layer of robustness as well, so
that overflowing negative values are not returned to the client.

Svn r1306 has the fix ready for the next release.
