Subject: git-gui: Don't crash when starting gitk from a browser session
X-Git-Tag: gitgui-0.8.4~4
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=906ab7f6c03764423adef6c0e4d77442405adc23;p=git.git

git-gui: Don't crash when starting gitk from a browser session

If the user has started git-gui from the command line as a browser
we offer the gitk menu options but we didn't create the main status
bar widget in the "." toplevel.  Trying to access it while starting
gitk just results in Tcl errors.
