Comment:

 From the backtrace it looks like the Qt bug where ~QSqlQuery which
 eventually calls mysql_next_result() in QMYSQLResult with a NULL handle.
 This only happens with a MYSQL_VERSION_ID >= 40100 when we have an invalid
 DB connection.

 Note: This does appear to be fixed upstream though I don't know when, see
 http://qt.gitorious.org/qt/qt/blobs/master/src/sql/drivers/mysql/qsql_mysql.cpp
 On line 420 they have added two null pointer checks.
