[postgis-users] Mezogis is closing when using a database

["Daniela Stärke"]

Hi Alex,

wow I probably found a bug, I am amazed. 

OK I made a new database which some geometrical form in it and tried to  start it with mezzogis. But as expected I received the same messages as before.

In the appendix of this email you find the dump-data of my database. It is just a simple one.

Here are the neccessary information to start the database:

the user: testuser ,
password: das ,
database: neutest ,
port: 5340

thanks for your help

Daniela
