BUG: column view in agenda -- marker does not point anywhere

Hi Carsten,

It seems today is bug reporting day :)

| right arrow   | to Estimated Effort field       |
| S-right arrow | to set the value                |

Each time I set the value I get the error: 

org-columns-update: Marker does not point anywhere

but it does work and update the task property so it's not harming
anything in org-mode data that I can see - it just beeps and displays
the message which is confusing.

This also breaks C-x ( macros which I use alot when repeating the same
actions on multiple tasks.  When the error displays the macro recording
terminates which is a little inconvenient.

With the cursor on a task in the agenda

| Keystroke     | Notes                             |
|---------------+-----------------------------------|
| C-x (         | Start macro recording             |
| right arrow   | to Estimated Effort field         |
| S-right arrow | to set the value (displays error) |
| C-x )         | to stop recording                 |
|---------------+-----------------------------------|

This issues the error

kmacro-end-macro: Not defining kbd macro
