Reopening SVG world map makes it blank

[Alexey Proskuryakov]

Steps to reproduce:
1. Open http://apps.arcwebservices.com/svgviewer/map.html
2. After it loads, press Enter in the address bar.

Results: the second time, the map doesn't appear.

JS Console shows an exception (Null value) in this line, which casts a shadow on XMLHttpRequest:

        var importedNode = document.importNode(this.xmlRequest.responseXML.documentElement,true);

This is not 100% reproducible, but happens fairly often.

Further testing shows that responseXML is null because the response document is invalid, and it's invalid because the request is incorrect. 

$ curl -I "http://apps.arcwebservices.com/svgviewer/awslive?ds=ArcWeb:TA.Streets.US&sf=160000000&w=0&h=0&a=0&ocs=0&cmr=-100|10|0|0|160000000|0|9&dc=0|0"
HTTP/1.1 400 Invalid width ("w") parameter value: 0. The value should be a positive integer, not greater than 8192.

This now looks like a duplicate of bug 7722 to me.

100% reproducible on my nightly build.

Emptying the cache allows the page to reload, when pressing enter on the address bar.

After that the bug re-manifests.

Webkit:
Safari 3.0.4 5523.15 (nightly build for 2/28/2008)
OSX 10.5.2

Changed component to SVG, so it shows up in my all-svg-bugs search.

The link is not valid anymore. Is there site to reproduce the problem?

Closing the bug since we don't have a test to reproduce the issue :(
