[karalabe]

Thanks for the report. We've seen a similar crash just yesterday. It originates from an underlying library that did some black magic :P The library was fixed since and I've just opened a PR to pull in the changes into go-ethereum too. Should be fixed today.

[karalabe]

The fix was merged into master, please rebuild and see if it works now.

[compasses]

Great, it's Ok now thanks.
