Error while running calibre with source

[Lev667]

hi,
I've upgraded to the new version of calibre,
and downloaded the new source code (and didnt make any changes to it)

When I try to download new news feed I get this error:

Traceback (most recent call last):
  File "C:\calibre\trunk\src\calibre\gui2\__init__.py", line 250, in dispatch
  File "C:\calibre\trunk\src\calibre\gui2\actions\fetch_news.py", line 60, in scheduled_recipe_fetched

  File "C:\calibre\trunk\src\calibre\utils\magick\draw.py", line 96, in save_cover_data_to
TypeError: must be convertible to a buffer, not Image

When I remove the CALIBRE_DEVELOP_FROM from the environment variables,
it's works fine.

what could be the problem?

thx.

Ticket #9286 created, this seems to be a regression with 0.7.48.

It seems to be a problem with changes Kovid is working on, done after 0.7.48. Until he fixes it, you must either run from binary or back out changes in revision 8342. Don't back out changes any further than 8340.

Fixed, I committed a change at 1:00 AM last night, this is the result
