Umbrello crashes when multiple objects are copied and then pasted

This bug was also reproduced on umbrello 1.5.4 by a friend of mine.

Steps to reproduce:
1. Create any diagram with two objects of any type
2. Select these two objects _by dragging a rectangle with mouse around them_
3. Copy to clipboard
4. Paste
5. Kaboom

Using host libthread_db library "/lib/libthread_db.so.1".
(no debugging symbols found)
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]
