Thanks for the suggestion.
Yes, you are right. It is an application that loads plugin components to 
do the actual work. The plugin (there is only one at the moment) and the 
application are both build in the same mode. Your reply did give me an 
idea for one more thing to test: removing the plugin from the plugin 
directory so it is simply not loaded does not solve the problem. In 
debug mode, the program will simply run without any available usefull 
components. That would mean the issue is not in the plugin, but in the 
main application. That does narrow it down considerably :-)

I will keep looking...
