Beam from the same archive used to work just fine some time ago. Could be some kind of compatibility problem.

Works ok in hrev43684.

[diver]

It has been broken somewhere between these revisions:

hrev43768 - works
hrev43798 - crashes.

[diver]

BTW crash happens on toolbar mouse over.

[diver]

hrev43773 is the first crashing revision.

[anevilyak]

The ABI break is due to the additional members added to BControlLook. If Beam is making use of that class, then an updated package should probably be built, as it's currently considered private/experimental.

[humdinger]

Newly built optional package "Beam-1.2alpha-x86-gcc2-2012-06-04.zip" fixes the crash. Committed with hrev44224.
