[solved] webview unload causes crash

[clogwog]

i'm not sure if this is a bug and needs to be reported or if i am doing something wrong.

I'm using a WebView in QML and whenever it unloads the whole application crashes
( http://doc.qt.io/qt-5.4/qtwebview-index.html)

simplest reproducible at:
https://github.com/clogwog/webview-crash-on-unload

it uses a StackView (but i found the same problem using a loader)
just run the app under ios or ios-simulator and go 1) forward (to load the webview) and then 2) backward to unload it.

the error i see is :
@program received signal -111, thread:9b16d;qaddr:39ddead0;00:04000000;01:b0535016;02:00000000;03:7c986202;04:4b9fd500;05:1c6c5816;06:88000000;07:d4946202;08:40989d37;09:cda32d00;0a:d89f5516;0b:f09e5516;0c:accc1601;0d:cc946202;0e:0f8c6200;0f:e61d0a00;10:30000000;metype:1;mecount:2;medata:1;medata:4;

bug was a duplicate and it has already been fixed in qt 5.4.1
i just downloaded 5.4.1 and on testing the problem has indeed been fixed.
