Using Replace Reference only works once on Linux

Using the Replace References option to replace one asset with another, the window does not close/refresh properly. This causes the window to stay on the screen although it cannot be interacted with.

Reported using Mint Cinnamon 17.3
Internal machine uses Ubuntu 15.10 and has not reproduced this issue.

Workaround provided by AH reporter:
"When the replace references window is used for the first time, it leaves an invisible but interactive version of itself. If this window is closed (I've done it by trial and error, clicking where the viewport doesn't respond) then the window can be opened and used again. The same method works for subsequent uses as well."

1. In a project, open the content browser.
2. Select two or more assets of the same type.
3. Right click one of the selected assets, and go to Asset Actions -> Replace References
4. Use the dialog normally. When the action is complete, the window will vanish but leave a blocking square where it should have spawned a new instance of itself.
