[Qt-interest] QSQLITE problems on clean install

[Jason Woodall]

On a machine where the application runs fine:
ConfigManager::init: libraryPaths(): 
E:/SVN/trunk/libraries/qt/4.5.1-base/plugins, 
E:/SVN/trunk/bridges/app/app/Release

2 paths are: qt plugin path
and
application directory

If I remove the sqldrivers folder from: 
E:\SVN\trunk\libraries\qt\4.5.1-base\plugins
the application fails in the same way as my base XP machine.  If I then 
copy that dir and contents to E:/SVN/trunk/bridges/app/app/release (note 
upper and lower case difference), then it works fine.


On a clean XP machine:
ConfigManager::init: libraryPaths(): //nas/support/jwoodall/app/test1

Where: //nas/support/jwoodall/app/test1 is the application directory and 
contains:
