Split from #336:
managed to crash client by opening menu in kcalc and dragging kcalc while its menu is visible. This is not very easy to reproduce but I hope that the crash log may reveal some details:

We should not be sending those invalid dimensions to the client!
dimensions too big: 165898320x110598880)
And ideally, we should detect this problem before we store the dimensions in our data structures as this may well cause other problems.
Can you please try both and confirm that the crash is prevented? (even so, I will keep this ticket open so I can find a proper solution - this is more of a temporary workaround)
Not heard back, closing. Feel free to re-open.
Sorry for not being able to test your fix. I'll try to reproduce with 0.10 to make sure if it was fixed. Thanks.
