It doesn't happen every time. After some time I try to run atop and it works. I suspect that some combination of gathered data makes trouble.

it is not always reproducible here, but it happens quite often.
newer versions seem to fix thin problem (e.g. 2.2) -> i have therefore created a stabilization request: Bug 590466
see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=778598 is upstream bugged, please remove
this bug should be closed as the affected version is not longer in the portage tree.
Affected version is gone. Please file a new bug if you still experience the reported problem. Thanks.
