Bug 1027073

There are a number of "Invalid null key" messages which may be related.  They seem to come from:

(gdb) print type
$2 = (const QCString &) @0x7fffffffd130: {m_data = 0x0}

So we may at least be able to avoid a segfault by checking for a non-null "type", but I suspect that this is a symptom of another issue.
