Hi,
when running some experimental stuff I got SIGSEGV on first pull() from an
event channel.
I created an event channel connected to a pull supplier (a `long´ random number
generator) on one end and to a pull consumer on the other one. When pulling
from the channels reading end I get exactly one random number - then the event
channel daemon (eventd) crashes with SIGSEGV. Here is a stack backtrace:

The crash is reproduceable each time when using a situation as described above.
My configuration:

Is there any help? Thanks
