Oh, I did try that. Everything works fine when GC is disabled.

At the point when it gets collected, it's still in scope as a local
variable of the pyt

I've noticed in the past that the garbage collector often
kicks in right after a query or so. Probably because of
some time that has passed or something like that.

which version of PyQt are you using ?
When in older versions (I think something like 2 releases ago),
the garbage collection kicks in in a thread and it deletes
a QObject from another thread, this object was deleted
immediately, while in recent versions those are deleted later
on in the event loo
query = QtSql.QSqlQuery()
if not query.prepare('select %s from %s where %s' %
(','.join(field_names), table, self.key_expr(table))):
I get 'RuntimeError: underlying C/C++ object has been deleted' on the
second line, with low probability. Sometimes it just segfaults instead
while i
