Fatal error on Zelemir fight start

[coyot]

Map 21 - once I start the battle and place my units down, when Zelemir prepares to thrown a lightning bolt at me, I get the following:

Error 1069, context U.gfx(UI__buttons__spell_icon_lightning_1).
stack trace: null.

Could anybody running the test build 0.9.04 try to reproduce this? I get it with both an old level40 party save and my new game started under the new build - and I get the error the moment I summon any character (and therefore give Zelemir a target).

Edit: Bug 360

Reproduced it myself yesterday, it'll be fixed in 0.9.05
