opening preferences raises a null pointer exception with Java1.5

[anonymous]

when opening preferences window on recent versions, we get the following exception:

Please attach your config file.

I also tried without the preferences file (removed), so starting with all defaults. And the same happens.

Does help removing "colors." in the line 197? It is superflous anyway.

In r1504. Please reopen when not fixed.

This solves the exception . But the first color (background) is not editable. When selecting the first line in the table, the buttons "choose" and "set to default" are disabled. All other colors are ok.

[stoecker]

In r1505.

Works fine now. Thanks !
