I have another problem on MacOS Snow Leopard and MacOS Mavericks (MacOS Lion (10.7.3), Windows and Linux work fine):

When my application starts, it takes about 60 seconds, where it normally takes less than 10 seconds. The console output is somewhat cryptic:

• *** __NSAutoreleaseNoPool(): Object 0x1012e2a30 of class QNSView autoreleased with no pool in place - just leaking
• *** __NSAutoreleaseNoPool(): Object 0x100634240 of class NSTextInputContext autoreleased with no pool in place - just leaking
• *** __NSAutoreleaseNoPool(): Object 0x1012f3a30 of class NSCFArray autoreleased with no pool in place - just leaking

and so on...

Checking in my code, following instruction is the culprit:

@statusBar=new QPlainTextEdit();@

Above instruction makes the start-up process stall for almost 60 seconds. But the widget finally works fine, and the application runs at normal speed.

Removing that instruction makes Qt stall at some other place, which makes me think that it is linked with some internal initialization that Qt might be doing wrong.

Thanks for any advice
