Tags with spaces is causing a seg fault:
"<a> <b>" = Seg Fault
"<i> <b>" = Seg Fault
"<i> <img>" = Seg Fault

Tags next to each other without spaces are fine:
"<a><a>" = OK
"<a><b>" = OK
"<b><a>" = OK
"<a><i>" = OK
"<i><b>" = OK
"<i><img>" = OK
"<a><img>" = OK

Some tags with spaces work fine:
"<i> <i>" = OK

Original string I found this bug in:
<img src="http://" style="margin-right: 3px; display: inline; vertical-align: middle;" height="20" width="20"> <a href="/services/alerts/">Text</a>

This was was no longer reproducible once I updated to the latest CVS libtidy from sourceforge so I'm going to close it. Anyone else who cannot upgrade can try the patch attached to the bug report URL that is in the comments.
