Icons on buttons in Thunderbird's mail toolbar are almost invisible when using Radiance theme

[Christopher Kyle Horton]

When setting the theme to Radiance in Ubuntu's Appearance menu, the icons on the buttons in Thunderbird's mail toolbar become almost impossible to distinguish from their background unless moused over. See screenshot.

Here's a comparison screenshot of the same area when using the Ambiance theme, in which case the icons are clearly visible.

[Chris Coulson (chrisccoulson)]

Works fine here, as expected. Did you restart Thunderbird?

[Christopher Kyle Horton (christhehorton)]

...actually, I had not. And restarting Thunderbird does restore those icons to how they're supposed to look. Thanks for the tip.
