Comment 3 for bug 266258

Originator: NO

In Debian, we fixed that problem with the following patch and running the
following withlist script on all mailing list on upgrade. Let me note in
passing that the code for clearIndex looks very suspicious: it takes an
"index" argument but completely ignores it. It should probably clear its
argument and not be hardcoded to clear the thread index.
