[Qt-interest] Hidden exception occuring in 4.7.2 "The interface is unknown"

[Tony Rietwyk]

Hi Everybody, 

I've recently upgraded from 4.6.0 to 4.7.2, running on Win XP using VS 2008.  The following message appears in the debug output: 

First-chance exception at 0x7c812afb in myapp.exe: 0x000006B5: The interface is unknown.

The code continues to run without error, and luckily the debugger does not stop.  The message appears when first using QNetworkAccessManager, or loading the help files, whichever comes first.  I searched the Qt bugs for "The interface is unknown", but there were no matches.  

I'm just curious why it appears! 

Thanks

Tony
