Version: 1.4.2 (using KDE KDE 3.4.2) When classes are deleted from the "logical view" branch of the UML model tree, UML crashes. Sometimes it crashes only at the second deletion but it is easily replicatable.
Fixed on the KDE 3.5 branch, see http://bugs.kde.org/show_bug.cgi?id=110843#c13 *** This bug has been marked as a duplicate of 110843 ***
