Problem with SqLite and Qt

[wysota]

I do have the sqlite plugin. It came as I installed SUSE 10.2 development distro, otherwise I would not have been able to run sqlite from the command line.

Wrong. You're mixing sqlite library and qsqlite Qt plugin. Jacek was asking about the latter. Please list the content of your plugins/sqldrivers subdirectory of the Qt root install directory.

I also notice that the database object is defined twice. Once as a mainwindow member and again independently. What is that all about? DB is ONLY a mainwindow public member and the createConnection() is in the Mainwindow code. It should not have created a new object independent of mainwindow.

Jacek has already pointed that out in one of his previous posts - you declare a local variable, thus the pointer declared in the main window is still invalid - that's the reason of your segmentation fault.
