           Summary: Notable leaks in QtWebkit - from Qt library
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: Kelemen.Balazs.3 at stud.u-szeged.hu


I tested WebKit's Qt port on Linux with Valgrind to search for memory leaks. I
modified QtLauncher by using the QtWebKit API and I used the loadFinished
signal to load URLs from a list file one by one. I found several notable memory
leaks (one of them is bigger than 3MB).
The attachment contains the call stacks (outputs of Valgrind) and my comments
which show the points where the execution crosses the border of the source code
of WebKit. (In some cases the traces were almost the same therefore I kept only
one of them in the log file but the zip files contain all different traces.)
Unfortunately, I cannot decide whether these are Qt bugs or WebKit uses Qt in a
bad way.
