Regular expression: replace all and undo bug

[Wosven]

Hi,

When searching numbers separated by spaces to replace those by non-breaking spaces, it's fine using only "replace", but "replace all" do errors.

Using "undo" to clean the mess is worste  
(and many "undo" hang the app)

Hi Wosven,

We found this last week and, I hope, fixed it. Could you try again with the next update.
