I agree this belongs to the qt frontend as stated in the wiki

Don't know why such a simple thing, that already has a patch working again 
poppler code has to go to the frontends, isn't code duplication bad?

I don't agree in hardcoding it to the wrapper, IMHO it is the application that 
has to provide the plugabble error function, someone may even want to show 
all error in a popup. So my suggestion is include my patch and let the 
application to the rest if it wants to do it.

I would prefer building first against the poppler tree and to the change after 
to poppler-qt

I had already verified first hand that it fixed a problem, you just had to ask 
for a test case, you did not.
