Bug #55086	Double-click Workbench File locks up PC indefinitely

Status:	Can't repeat	Impact on me:	None

Description:
When I try to launch MySQL Workbench by double-clicking a .MWB file in Windows Explorer, Workbench opens, but then as the .MWB file is being loaded, the PC locks up.  The mouse and keyboard stop working, and the O/S becomes completely unresponsive (for example, inserting a CD or a USB device does NOT elicit any response from the O/S).  The only way to get my system back is to force a hard restart of the PC, which of course results in a loss of any data which wasn't saved at the time.  The only workaround is to open MySQL Workbench *first*, and then open the file using one of the means available within Workbench.

I first noticed this behavior in Workbench version 5.2.22 OSS.  Prior to that I was running 5.1.18a, and I did NOT notice this bug there, but that was on a 32-bit Windows XP SP3 machine.  When I recently installed 5.2.25 CE, the bug was still there.  I have only had 5.2.22 and 5.2.25 installed on the Win 7 PC.

How to repeat:
- Open Windows Explorer
- Double-click a MySQL Workbench File (.MWB)

I have no problems opening .mwb file uploaded on Mac OS X. It may be Windows 7 specific problem.

I couldn't repeat on Vista Ultimate X64 too.

Tested on Win7 HP x64. I have no problems opening .mwb with WorkBench file uploaded (either via file > open model or via doubleclick in OS)
