I belive that this happened because surf 115 was closing and tried it's history.

That's odd, it looks like *Terminal.activity* crashed from your report.

Can you reproduce this crash?

I can't directly reproduce this error. I am pretty sure that it is due with a problem of memory allocation in surf. A large percentage of the time when I close surf 115 a segfault happens somewhere in sugar.

lucian though that the segfault is cause by surf when when it writes the history.
