However I noticed that if you have a connection to a shape in a group the
connection does not autoupdate when the group is moved. It works with shapes
not in a group without problems.

Comment 2 Halla Rempt 2012-05-04 08:22:20 UTC

I'm not always getting updates correctly even with simple shapes; sometimes I need to click on the connection shape, sometimes it works, sometimes I have to manually repair. But I do not get a crash and the backtrace is outdated.

Maybe this only happens with some specific shapes?
