Re: BUG #14897: Segfault on statitics SQL request

Sorry. I didn't find the way to create an attachment in the interface.
You can find the database dump as attachment.

I didn't tweak database. I use default Archlinux configuration (which
should be PostgreSQL default configuration).

I will try to get a stack trace.

Regards.

Vincent
