Hi,
when I try to apply patch #2024 (gantt_edit_5_v1-1-1.patch) from this thread http://www.redmine.org/boards/3/topics/22288?r=22292#message-22292 I get the following error:

Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
------------------------- |41,7 +42,7 @@ | <% zoom = 1 | @gantt.zoom.times { zoom = zoom * 2 } | |-subject_width = 330 |+subject_width = 280 | header_heigth = 18 | | headers_height = header_heigth

File to patch:

could someone suggest what I'm doing wrong?

thanks,
