Comment 1 Oliver Kellogg 2007-05-30 08:12:49 UTC

Created attachment 20722 [details]
valgrind log

While I'm having a problem recreating the crash using umbrello r669259
from branches/KDE/3.5/kdesdk, valgrind does report uninitialized values
when moving a multiple selection containing associations on a class diagram.

Comment 2 Oliver Kellogg 2007-05-31 01:22:41 UTC

SVN commit 669987 by okellogg:

FloatingTextWidgetController constructor: Initialize member variables.
This fixes the valgrind warnings exposed in attachment 20722 [details].
I have not been getting the reported crashes using r669259 of
SVN branches/KDE/3.5/kdesdk/umbrello.
Could someone please verify that the bug is really fixed, thanks.
