Hi Steve, When I remove all my local database files problem goes away. So problem appears to be in a local database. I narrowed it down to one .ldb file. But the problem doesn't seem to be as simple as one particular signature in that file. I can remove signatures until the problem goes away,

Hi Benny, We use bugzilla as the primary bug tracker. We know about github too, but bugzilla is preferred. This is mainly because bugs that are ClamAV vulnerabilities(crashes and other denial of service) should not be widely disclosed until fixed within a released version for obvious reasons. In
