Creator QML Designer blocking/non-responsive when working with QML design view

When attempting to work with a Qml file in the Creator embedded design tool. Creator becomes unreponsive for about a minute when taking action (e.g. changing the currently viewed state, etc.)

In DebugView, it becomes responsive again only after the following is output:

[8700] Process crashed: QTimer(0x274afd58) exitCode: -1
[8700] QIODevice::write (QLocalSocket): device not open
[8700] QIODevice::write (QLocalSocket): device not open
[8700] QIODevice::write (QLocalSocket): device not open

This appears to be a regression or similar issue to QTCREATORBUG-21372 which was resolved in 4.8.1 where Creator is searching the network for resources due to malformed paths. The unresponsiveness does not appear to happen when the computer is disconnected from the network.

Since this happens often when working within a single page, it renders Designer nearly unusable as any arbitrary action seems to precipitate a freeze.
