ibus max cpu and freeze when typing in firefox location bar

[Chris Hatch]

When using Ibus for text entry into the firefox location bar I regularly get freezes of 5 - 20 seconds. Looking at 'top' both ibus and firefox are maxing out CPU. On return from the freeze I can type freely but if I leave and return to location or I go to a new tab location bar the problem will often but not always occur again.

I don't see this in the search box (Ctrl K) and I don't see this in other software using IBus - eg. Gedit, chrome location bar, terminals..
