Win7 SP1; Git identifies itself as version 1.8.4-preview20130916.
I copied the Git Bash shortcut from the start menu to the root of a
Git repository (no remote part). I use the advanced context menu. For
other files in the directory, it works fine, but hovering over the Git
GUI option of the Bash shortcut's menu causes a hang and this error:

It seems odd that it occurs on hover, but nothing else - time or other menu items - trigger it.
