Agenda column view fails with "Invalid search bound (wrong side of point)"

Agenda column view fails with "Invalid search bound (wrong side of point)"

[Bernt Hansen]

Hi Carsten,

I'm using org-mode from commit 001e6df25c75e2566ad9c083341b4906e86cd8d8.

In the agenda I'm doing a search for tasks with no effort estimate using

,----
| Headlines with TAGS match: Effort={^$}/!NEXT
| Press `C-u r' to search again with new search string
`----

and entering column mode to enter effort amounts.  For some of the NEXT
tasks it works fine but for others (this is the 3rd one this morning)
when I'm entering the estimate using a quick insert key (3 = 0:30) I get
the following error:

    Invalid search bound (wrong side of point)

The agenda is then displayed without column mode and hitting 'g'
refreshes it with column mode displayed so I can continue entering
estimates for the rest of the tasks.

Debug output follows from uncompiled org-mode sources.  Hopefully this
is enough to understand what is going on.  I'm not sure why some tasks
work and some don't.
