Wrong overflow cropping in element with border-radius on Opera

Question

Ok, so I've made this FC Barcelona CSS logo and everything works fine under:

• Firefox 13
• Chrome 20
• Safari 5
• IE 9

BUT on Opera 11 (and 12 too) those blaugrana stripes are not cropped. I have tried many configurations, with and without additional wrapper, but I couldn't get it work.

HTML:

<div id="blaugrana_stripes_container" class="abs border_black fill_purple cropper layer9 rounded">
    <!-- Wrapper needed for some browsers to crop overflow properly -->
    <div id="blaugrana_stripes_overflow_cropper" class="rounded">
        <div class="blaugrana_stripes fill_purple border_blue"></div>
        <div class="blaugrana_stripes fill_purple border_blue"></div>
    </div>
</div>

related CSS:

#blaugrana_stripes_container, #blaugrana_stripes_overflow_cropper {
    width: 244px;
    height: 244px;
    text-align: left;
    -moz-border-radius: 155px 155px 134px 134px;
    -webkit-border-radius: 155px 155px 134px 134px;
    border-radius: 155px 155px 134px 134px;
}
#blaugrana_stripes_container {
    left: 36px;
    top: 62px;
    border-width: 2px;
    -ms-transform: scaleY(0.79);
    -moz-transform: scaleY(0.79);
    -webkit-transform: scaleY(0.79);
    -o-transform: scaleY(0.79);
    transform: scaleY(0.79);
    z-index: 3;
}
#blaugrana_stripes_overflow_cropper {
    overflow: hidden;
    white-space: nowrap;
}
.blaugrana_stripes {
    height: 100%;
    width: 35px;
    border-width: 0px 35px 0px 35px;
    margin-right: 35px;
    display: inline-block;
}
.cropper {
    overflow: hidden;
    font-size: 0;
    margin: 0px;
    padding: 0px;
    border: none;
}
.abs {
    position: absolute;
}

I've copied it here because there's a lot of code, so maybe it will help. Above I've skipped classes used for decorating (border_black fill_purple), z-indexing (layer9) and javascript mechanisms (rounded) because I think they're not related with problem.

Of course everything is viewable via Firebug or other developer tools on the demo site.

Any suggestions?

I don't know why this is buggy in Opera, but you can use gradient (see code below). It is not working in IE (tested with version 9).

.blaugrana_stripes{display:none;}
#blaugrana_stripes_overflow_cropper{

background: #0b2f89;
background: -moz-linear-gradient(left,  #0b2f89 0%, #0b2f89 14%, #980f39 14%, #980f39 28%, #0b2f89 28%, #0b2f89 42%, #980f39 42%, #980f39 57%, #0b2f89 57%, #0b2f89 71%, #980f39 71%, #980f39 86%, #0b2f89 86%, #0b2f89 99%);
