nil check m_documentUnderMouse and take the "local file" case if it's nil
I can't reproduce any crash here. ??
$ rpm -q arora qt
Where did you get qt-4.5.2-21.fc11.x86_64? The newest qt in the F11 repositories is qt-4.5.2-3.fc11 which does have the bug.
Oh, yeah, my own backported build of what's currently in F-12/rawhide.
Still, the bug *should* still be present there. Do you have a recipe to reproduce the crash?
In the meantime, the patch looks fairly sane, but I'd rather have comment from one of my fellow qt maintainers before applying it.
If you want to test for yourself, the newer experimental qt builds are here:
in the unstable repo
Tested with qt from http://kde-redhat.unl.edu/apt/kde-redhat/fedora/11/ and can still reproduce. Please try the following:
-open arora (I use arora from git, but the bug was present using 0.9.0 and 0.10.0 as well)
-click and drag a bookmark from the bookmark bar.
-drag the bookmark over the webview and back out.
-arora will crash.
The patch is backported code from qt-4.5.3 if it make review any easier.
> -arora will crash.
confirmed, thanks for the test-case.
> The patch is backported code from qt-4.5.3
oh cool, that puts me at ease then. will apply.

If the fix is already in 4.5.3, the best solution would be to get Qt 4.5.3 out ASAP (but of course we need to sort out that translations mess). But sure, backporting fixes from 4.5.3 to 4.5.2 is safe.
the fix is already included in 4.5.3.
It's been a while. I din't realize the bug report was still open. Verified fixed with current Fedora 12
