TypeError in qx.ui.mobile.core.EventHandler after update to qooxdoo 1.5

After updating to qooxdoo 1.5 I am seeing this error:

Uncaught TypeError: Expectin开发者_如何学JAVAg a function in instanceof check, but got #<HTMLDocument>

:8080/qooxdoo-1.5-sdk/framework/source/class/qx/ui/mobile/core/EventHandler.js?nocache=0.38786523090675473:245

Strange thing is, that I am not using the qx.ui.mobile.* classes at all. This is with a source-all build and "qx.debug" set.

---

As for including the qx.ui.mobile.* classes, this comes from using the source-all job, which includes, well, all known classes, also the qx.ui.mobile.* ones. Try using the normal source job, which only includes the classes necessary for your app.

As for the error, please open a bug report at http://bugzilla.qooxdoo.org. Please specify the OS and browser you are using when you get the error. If possible, supply a minimal Application.js (or a Playground link) that reproduces the error. Cheers.
