> I'm wondering how your experience is on Qt 4.6?  

On the "production" side of things, I've been running 0.23-fixes on Qt 4.6.2 for 
months, without issues, on XP, Vista, and Win7 (x32 and x64).  I have yet to 
update my 0.23-fixes build VM to Qt 4.6.3, so I can't say if that has changed 

My trunk build VM has Qt 4.6.3, but I haven't tested beyond compile and launch 
because I don't currently have a trunk backend.  That said, I haven't had any 
problems starting the frontend and getting the expected DB mismatch screen.

I did encounter app initialization problems when I switched to gcc 4.4, but that 
was fixed by updating MinGW bintools to 2.20.  Maybe run "/mingw/bin/ld 
--version" just to make sure the update isn't being skipped somehow?  Or make 
sure there aren't any other copies of ld in the path?  *If* this is the same 
issue, another workaround is to disable ffmpeg's use of __attribute__((cold)).

My build VMs are WinXP; perhaps I'll try building on a Win7 VM to see if that 
makes any difference.
