Hi,

The issue tracker is only if you have a simple, standalone test case. But your 
test code is just connecting to the database, so with that alone I can't 
reproduce the problem of course.

Could you use the mailing list next time instead of filing a non-reproducible 
bug? There, you can send the database file (we would need that). Or send it to 
me directly.

Regards,
Thomas

Hi,

Thanks a lot! You are right, this is an endless loop, it is a bug introduced in 
version 1.4.186. I have fixed this bug now (in the trunk).

Regards,
Thomas
