>#47 0x00007f76771ffc5d in QDialog::exec() () from /lib64/libQt5Widgets.so.5

and here's our problem.
execs from the main thread in QML are bad.

I'll see if I can rework our KIconDialog wrapper
Comment 2 David Edmundson 2015-08-02 22:33:09 UTC 
Git commit 7a514de428ef1da5fa14dc004775c21b3b710e7d by David Edmundson.
Committed on 02/08/2015 at 22:32.
Pushed by davidedmundson into branch 'master'.

Use the better implementation of IconDialog

For some reason we have two IconDialog's exported to QML.

One in KDeclarative, one in Plasma-Frameworks/platformcomponents.

The one in plasmacomponents performs an exec() in the main thread from
QML which is a very bad idea. the one in kdeclarative is good.
