I have uploaded a new version of EventCalendar that adds a little output for debugging and should at least start (even though it might not display events).

As I cannot reproduce the above bug on my system, you'll have to help me a little. It would be most helpful if you ran EventDatabase.py from the command line and sent me the complete output. You can find an email address on my homepage...

The problem is this call in EventCalendarScreenlet.py:

ctx.mask_surface(group_pattern.get_surface(), \
shadow_x_offset, shadow_y_offset)


Specifically group_pattern.get_surface()

I'm not sure what went wrong but in my distro (Ubuntu) since the last version (Karmic) there's some changes in librsvg and python-rsvg that might have caused the issue.

For the users, edit the file EventCalendarScreenlet.py and comment out those two lines by adding the symbol # at the beggining of each line (you can also delete them):

#ctx.mask_surface(group_pattern.get_surface(), \
#shadow_x_offset, shadow_y_offset)

It works here..

Forgot to add, those lines only loads the SVG file for the background.
No other functionality is lost by deleting the lines.

Hope this helps.
EventCalendar will work fine with Ubuntu 9.04, but won't work with Ubuntu 9.10 (amd64 installation, alpha5).

from this 2 lines of output
"name = result.group(1)
AttributeError: 'NoneType' object has no attribute 'group'"
it seems like result.group doesn't exist. that means that object result isn'n initialized, and because of that it doesnt contain attribute group...
hope that helps... :S

loving the concept of this screenlet though. hopefully you can work out this bug so i may use it!

I can't make it lunch ... it says it's working but it isn't seen anywhere

same thing happen to me. Installed when I run it did not show.
