design fails w/css : NumberFormatException for input "6.5"

[vanort]

I'm unable to use the GUI tool on any widgets. Even a newly created, empty widget gives produces a WindowBuilder internal error when switching to design view. It works if I comment out my .css file. The error references a string "6.5", but grep turns up no such string anywhere in my project, including css.

Using Eclipse 3.5 with Sun Java 1.6 on Linux.
Registration info says Product Version: 7.1.0.200906301927[200906301927]

Tried uninstalling GWT designer (by removing com.instantiations.* from the plugins dir and reinstalling). The only solution I've found is to comment out the CSS, however I'd rather not have to do that each time I use GWT-designer..

WindowBuilder encountered unexpected internal error. Please contact support.

This exception (which was unique to GWT under Linux) was fixed a couple of weeks ago.

Please update to the latest v7.1 build and try it again.
