The line in the Key map in a sessionname.conf-File that should read:
DismissBuffer = u'control+win+"'
DismissBuffer = "u'control+win+'"
In my humble opinion it should read:
DismissBuffer = 'control+win+"'
Sorry, I am not a programmer but someone who looks at the config-Files. After changing these settings the startup process was better.
I am working with a german keyboard and also can't use the edit-function of the keystroke manager right now.
