karbon (2.5.2) on KDE Platform 4.9.2 using Qt 4.8.2

- What I was doing when the application crashed:
How to reproduce:
* draw two different Paths (simple path tool; fresh install)
* select both layers "Shape"
* group them with Ctrl+G
* expand the layer "Group" and drag&drop one of the paths BETWEEN "Layer" and "Group"
-> after a very short time (ca. 200ms) the program crashes (until then it seemed to work)

I tested this bug on different Ubuntu variants both virtual and not virtual, it always worked.
This was never tested on an other hardware configuration, though I never had any unusual problems with crashing software.

karbon (2.9.2) on KDE Platform 4.14.8 using Qt 4.8.6

- What I was doing when the application crashed:
Pasted a group of objects (shapes and text).
- Unusual behavior I noticed:
The group elements were scatered around, not as the source.
