It's very odd that this would just start happening now.

This no longer occurs after fixing bug 12620.

However, the "bug" still exists.  It's possible to provide a bad values array which would hit this.

For example:

<animateTransform type='rotate' value=';10' />

is likely to hit this ASSERT.

I thought animation was turned off these days?  This shouldn't be a P1 if that's the case.

[Eric Seidel (no email)]

It's not possible to reach this crash on TOT since SVG animation is disabled via ifdef.  Downgrading to p2.

[Eric Seidel (no email)]

Animation is back on, this goes back to P1.

We've never seen those anymore in the past months. Closing.
