I have discovered this bug before :) It happened in EMBEDDED mode (and
according to your report in LOCAL, but not when connecting via IPC) when a
query is executed using PreparedStatement, but returns no result. In this
case engine believes that cursor in open, though a driver had different
idea. When the same code is executed with remote server, everything is ok.

I will commit the fix to HEAD and Branch_1_5 today and it will appear in the
next point release (probably somewhere within next two weeks).
