            Bug ID: 323227
           Summary: Changing the cursor using the terminal escape sequence
                    clears the profile name
    Classification: Unclassified
           Product: konsole
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: john at szakmeister.net

I have a plugin called vim-togglecursor that will let users change their cursor
shape when in insert mode on a terminal version of vim.  It's done using the
CursorShape escape sequence that Konsole supports.  What we discovered at work
the other day is that after launching a terminal version of Vim, the profile
name would be cleared (instead of being the default "Shell").  After some work,
we were able to narrow it down the escape sequence for changing the cursor
shape.  ISTM, that changing the shape in this way should affect the profile. 
Or, at least, when the shape is what the profile had originally set up, the
profile name should remain (the plugin does restore the cursor shape on exit
from vim).

Reproducible: Always

Steps to Reproduce:
1. Starts Konsole.
2. Select "Settings -> Configure Current Profile" from the menu.
3. Observe that the profile has a name and that the cursor type is setup as a
block cursor.
4. In the terminal, type: printf "\e]50;CursorShape=1\x7\e]50;CursorShape=0\x7"
5. The above should flip the cursor to a line shape, and then back to a block
shape.
6. Select "Settings -> Configure Current Profile" from the menu.
7. Observe that the profile name is now empty.
Actual Results:  
The profile name is empty after following the steps above.

Expected Results:  
I expect the current profile name to remain the same.
