[Sugar-devel] Copy from paint broken with Rainbow

[Daniel Drake]

Hi,

There is a Sugar-0.82 regression in that you can't copy a selection
from paint to the clipboard (using Paint's copy button). Reproduced on
OLPC OS 8.2 with Paint-23.
Disabling Rainbow solves the issue.

At the point of failure, a broken icon is created in Sugar's clipboard
tray and this appears in shell.log

Could someone running a more recent Sugar with rainbow setup please
test to see if this regression still exists?
cheers
