I have a consistent crash when editing a DMI file I created the other day.

The dmi file is just a black square. I added a new unnamed icon state, then edited the new state. Once I hit the back button on the DMI editor, the IDE crashes.

Looks like it's a null pointer exception.

Try opening this DMI file in Dream maker, double-clicking on the white square and then hit the back button. It has crashed every time I've attempted to edit the duplicate state.

EDIT: I thought I was on 1530, but it turns out I was still on 1529. This issue is not present in 1530. Sorry to waste your time.

In response to Ter13
Looks like I'll need more. I just tried creating a new icon, adding a state, flood-filling black, and I hit the back button, with no crash. This is in release-mode 513.1530.

[edit]
I missed your link. Trying that icon now.

[edit 2]
Nope, no crash for me there either. I'll try tracing your crash.

[edit 3]
Crash was determined to be due to the maptext bug from 1529.
