It's not a dolphin product bug. Other example:
Steps to Reproduce:
1. open kwrite (0,0 739,535), top left, left monitor
2. open system settings (230,342 1016,682), bottom right, left monitor
3. Use "Window List applet" and select the second command ("Cascade Windows")
Actual Results:
The window "system settings" moves for 1 sec to position (~10,~10) from (230,342) and crashes (disappears).
Please pay attention to the misleading German translation!
"Unclutter" means "anordnen" in German.
"Cascade" means "staffeln" in German.
If I want to "Cascade" the windows I use the second command ".. anordnen".
Could you try and reproduce this bug with a style other then oxygen? (please do post the backtrace if it crashes. If not then it's probably a oxygen bug) 1. open gvim (0,0 588,449), top left, left monitor
2. open kwrite (393,342 853,682), bottom right, left monitor
3. Use "Window List applet" and select the second command ("Cascade Windows")
Actual Results:
The window "kwrite" moves for 1 sec to position (~10,~10) from
(393,342) and crashes (disappears).

1. open kwrite (0,0 853,682), top left, left monitor
2. open kwrite (392,342 853,682), bottom right, left monitor
3. Use "Window List applet" and select the second command ("Cascade Windows")

I can't reproduce any of your cases (on trunk that is). The only difference i have is i'm on a single monitor setup and you seem to have more then one (since you mention left monitor all the time). So, that either means it's fixed in trunk (?) or it's an issue that only appears with multiple monitors. (or i'm testing it wrong) Created attachment 51724 [details]
TwinView example with no effect and no crash
Yes, it's a TwinView issue. Neither the command "Unclutter Windows" nor "Cascade Windows" of plasmoid windowlist do anything. In the upper left corner for a very short moment a repositioning is shown and instantly aborted. In this case no crash happens.

Created attachment 51571 [details] crash report Version: unspecified (using KDE 4.5.1) OS: Linux Window List applet with NVIDIA TwinView (Monitor 1: 1280,0 1280,1024; Monitor 2: 0,0 1280,1024): Neither the first command ("Fenster staffeln") nor the 2. command "Fenster anordnen" work as one would expect. Both commands worked correctly prior to KDE 4.5 (?) as far as I remember. Reproducible: Always Steps to Reproduce: 1. open firefox (0,0 1106,1024), top left, left monitor 2. open dolphin (35,0 1245,682), top right, left monitor 3. Use "Window List applet" and select the 2. command ("Fenster anordnen" in German). Actual Results: dolphin moves for 1 sec to position (~10,~10) from (35,0) and crashes (disappears).
