In the given example, but many other examples, nothing is rendered. Just a blank white screen.

Here are other examples that fail to render with the current build:
http://www.carto.net/papers/svg/navigationTools/index.svg
http://www.carto.net/papers/svg/gui/scrollbar/index.svg
http://www.carto.net/papers/svg/gui/slider/index.svg

and many more ...


Reproducible: Always

Steps to Reproduce:
1. load any of the specified examples
2. compare to the rendering in Opera9 or Batik
3.
Actual Results:  
nothing renders

Expected Results:  
I'd expect it to correctly render like in Opera9 or Batik.

It is a weird problem for after reloading a couple of times the image finally appears.

A regression window would be useful.

Seems to point to Bug 18333. If that doesn't make sense I'll retry.
I reloaded the 2007-01-30:11 build 40 times but could not make it fail.

Bug 18333 was correct. Between the page reloads you can see the page turn white. That did not happen in previous builds.
There are two bugs involved. The first one was Bug 18333 which made it fail sometimes and then Bug 369011 which made it fail nearly always.

Attachment: testcase

Comment 7

Attachment: testcase improved - red==fail, green==pass

Note that you don't need to reload to get the SVG to display, you only need to resize the browser window.

Comment 8

[tor]

The testcase and slider example were broken by the incremental XML checkin (checked building right before and after), the other two examples must have been broken by something else.

Comment 9

[tor]

Hmm, the examples are actually failing randomly in the "after" build.

Comment 10

[tor]

A combination of the patch I'm working on for bug 353172 and a patch to nsXMLContentSink.cpp (bug to be filed) fixes both the testcases and the carto.net examples.

Comment 11

[tor]

nsXMLContentSink bug is bug 370210.

Comment 13

[tor]

Both dependencies now in, all testcases here work.
