[Chicken-users] bb.egg problem

[Nico Amtsberg]

Hello everyone,

I figured out a problem using the bb.egg. The code given below fails under
the following circumstances:
holding the space key to toggle the first button continously gives the
following error after an amount of time (about 100 to 300 calls of the
callback)

Error: (for-each) argument is not a proper list: error in error

...more...
<eval>
<eval>
<eval>
<eval>
...

What I think I have figured out so far: 
without having set the key handler, program seems to run 
with key handler and explicit garbage collector in loop, program seems to run

Theese observations might lead to the wrong direction, maybe the garbage
collector just defers the problem. But Im clueless where and how to continue
debugging.

Thanks so far

Nico
