Reproducible crash in Windows 7. Rightclick menu issue.

[Twig]

Steps to reproduce:

Right-click System Tray Icon and Left-click About to bring up About dialog
Right-click System Tray Icon again and this time Right-click About. Ubuntuoneclient.exe will crash

This is on Windows 7 with all updates applied.

It is possible for it to crash with other combinations of clicks (especially right-clicking the menu once it has appeared). However, the method above will reliably cause a crash.

Marking as security vulnerability as not sure if the crash could be exploited.
