Description Johan Linde 2009-05-08 17:19:37 UTC

Version:           2.0 RC1 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.28-11-generic

1. Created shape, rounded corners, applied colors..
2. Created another shape, put on top of first shape.
3. Expanded first layer, then created new layer and named it 'green'
4. Moved second shape to new layer
5. Crash

Backtrace doesn't contain anythin useful I think.

Comment 1 Jan Hambrecht 2009-05-24 19:40:17 UTC

Unfortunately i cannot reproduce this anymore. Which version of Qt are you using?

Comment 2 Elián Hanisch 2009-06-09 00:03:45 UTC

I can confirm in trunk
just create two layers, add a shape, and move the shape to the other layer from the layer view docker

Qt: 4.5.0
KDE: 4.2.4 (KDE 4.2.4)
kde4-config: 1.0

backtrace says is invalid

Comment 3 Jan Hambrecht 2009-06-21 00:52:45 UTC

After some discussion on IRC it seems the bug is fixed in qt-4.5.1.

Comment 4 Elián Hanisch 2009-08-12 02:07:53 UTC

I can confirm it is fixed in trunk

Qt: 4.5.2
KDE: 4.3.00 (KDE 4.3.0)
kde4-config: 1.0
