wine crashes installing firefox

installing firefox 2.0RC2 for windows results in a crash. The installer's first window shows up, however clicking "next" onto the next window (licence window) results in the crash. console output is shown below.

This does not occur with the 0.9.23 package available using "http://wine.budgetdedicated.com/apt dapper main" as an apt source. I am confident that it did not occur with the winehq 0.9.22 deb.

The install was done after removing ~/.wine for both the ubuntu and winehq packages.

0.9.22-0ubuntu3

0.9.23~winehq0~ubuntu~6.06-1: (didn't complete install, as it incorrectly reports insufficant disk space-it does get past the licence crasher screen from the other install)
