Unspecefied error when accessing site settings for site based on custom template

Question

We have a problem for our SharePoint 2010 solution. Basically we run into the issue described here:

http://www.petestilgoe.com/2011/02/sharepoint-2010-create-site-from-site-template-where-alternate-css-url-is-set-unexpected-error-occured-accessing-site-settings/

or here

at least I think, but the fix (as described in the first one) is not something we can live with (as those who will be able to create sites won't have access to perform that fix), now in a response to that someone said one could rebuild the WSP file, but I am thinking that there must be a way to fix this through our solution instead.

Further more this is not an issue we see in our local development environment, now obviously those to are far from the same environment, but i still find it strange.

I think the accepted response on MSDN is from this post:

But our site is not a publishing site. This is how our style module looks in our "onet.xml"

<Module Name="Styles" Url="Style Library/styles" RootWebOnly="TRUE">
    <File Path="styles/core.css"  Url="core.css" Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
    <File Path="styles/print.css" Url="print.css" Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
    <File Path="styles/reset.css" Url="reset.css" Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />

    <File Path="images/boundaryindicator.png" Url="images/boundaryindicator.png" Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
    <File Path="images/green_print.png"       Url="images/green_print.png"       Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
    <File Path="images/logo.png"              Url="images/logo.png"              Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
    <File Path="images/red_print.png"         Url="images/red_print.png"         Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
    <File Path="images/sprites.png"           Url="images/sprites.png"           Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
    <File Path="images/yellow_print.png"      Url="images/yellow_print.png"      Type="GhostableInLibrary" IgnoreIfAlreadyExists="false" />
</Module>

Feel free to ask for more information. Ill try to share what I am permitted to.
