Description of Problem:
Bug in Mono1.2.5
There is a DropDownList in our WebUserControl. This DropDownList is not
repopulated from the ViewState after the 2nd PostBack. This problem does not
occur in ISS and Mono1.2.4. We encountered it after updating to Mono1.2.5

Steps to reproduce the problem:
1. Open website
2. Postback
3. Postback => Error 500

Actual Results:

System.ArgumentOutOfRangeException: Index is less than 0 or more than or equal
to the list count.
Parameter name: index 2
at System.Collections.ArrayList.get_Item (Int32 index) [0x00000]
at System.Web.UI.WebControls.ListItemCollection.get_Item (Int32 index)
[0x00000]
at System.Web.UI.WebControls.ListControl.LoadViewState (System.Object
savedState) [0x00000]
at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState)
[0x00000]

at System.Web.UI.Page.LoadPageViewState () [0x00000]
at System.Web.UI.Page.InternalProcessRequest () [0x00000]
at System.Web.UI.Page.ProcessRequest (System.Web.HttpContext context) [0x00000]


Expected Results:
Unchanged DropDownList content, similar to the content before the postback

How often does this happen?
Always


Additional Information:

I am attaching a small application.
This small application works on MS.Net and Mono 1.2.4_x
We have setup a server-application for this application at
http://monobug.yot-project.net/WebForm1.aspx.

Installed Versions:
libgdiplus-1.2.5_1
mod_mono-1.2.5_1
mono-1.2.5_7
