[webkit-dev] QWebNetworkManager triggering a memleak in Qt

[Adam Treat]

Hi,

I've checked and this appears to be the case in both Qt 4.3.2 and Qt 4.4 
snapshot...

==7746== 4 bytes in 1 blocks are definitely lost in loss record 5 of 507
==7746==    at 0x4022765: malloc (vg_replace_malloc.c:149)

QObject const*, char const*, Qt::ConnectionType) (qobject.cpp:2567)

WebCore::ResourceHandle::create(WebCore::ResourceRequest const&, 
WebCore::ResourceHandleClient*, WebCore::Frame*, bool, bool, bool)

==7746==    by 0x4970831: 
WebCore::MainResourceLoader::loadNow(WebCore::ResourceRequest&)

QObject is allocating memory for this queued connection that is apparently 
never freed.

Cheers,

Adam
