I've made a lot of investigation of crash when moving toolbar on my system.
There are two necessary conditions to reproduce the problem:
1. nvidia driver for xorg (when using other driver - vesa, nv or vboxvideo - there are no crashes).
2. using KDE4 as a desktop environment (when using KDE3 or Gnome there are also no crashes).
I've attached three screenshots of my desktop:
1. codeblocks-KDE4-nvidia.gif - before crash, using KDE4 and nvidia driver (it wasn't too ease to make such screenshot!)
2. codeblocks-KDE4-nv.gif - no crash, using KDE4 and nv driver
3. codeblocks-KDE3-nvidia.gif - no crash, using KDE3 and nvidia driver.
On the first picture you can see blue solid rectangle - it is the final position for toolbar, when moving it. On the other pictures this rectangle isn't solid, it is the shaded blue-white rectangle.
So, when I see the shaded rectangle, there is no crash, when I see solid blue rectangle, there will be crash.
Can anybody reproduce the bug?
