Bug #24675 Closing ODBC window after System DSN edit crashes comp

Description:
Hi,

This is a fairly simple and straightforward bug.  After installing ODBC connector 5.0.2 BETA I simply add a System DSN and after closing the "ODBC Database Administrator" dialog, windows crashes.

How to repeat:
1. install odbc connector 5.0.2 beta
2. add new system dsn odbc
3. close 'ODBC Database Administrator'

-whole thing come down in flames

Suggested fix:
ensure users can edit odbc setting from windows, this include closing of odbc form after settings successfuly committed.

Thank you for a problem report. Please, try to repeat with a newer version, 5.00.09-beta, and inform about the results.

Yes I was using 5.0.9.  I have now updated bug, cause the version was wrong.

Hi Jared and thanks for your report. We are aware of this and are working on a fix.

Committed as rev711.

The issue here is that there is a cache that initialized and free'd when the setup DLL is unloaded. Since QApplication is static, that is free'd when the compilation unit is unloaded. The order that this was happening was that the cache was being free'd first, but the QApplication expected to handle it and tried to free it again.

I reduced the scope of the QApplication to only when the GUI is shown.

Fix released in 5.00.10 beta.
