Bug Description

xchat-gnome bailed out ungracefully while removing Networks.

New install of xchat-gnome, removing Networks from the list that are there by default.

Highlight top Network in list - click delete - that one disappears and then immediately presented with the dialog box to delete the next with the "Delete" button already highlighted - press return key - expect to delete that Network - instead application crashes.

To be fair - this is on the latest 12.04 alpha - so can't expect things to be perfect :D

OK - just replicated this.

To replicate you need to select a Network other than the top one in the list and hit Remove - Remove in the dialog box - that network gets removed and then immediately presented with Remove dialog for next in list - press Remove on that dialog - app crashes.

Selecting the top in the list and removing works as expected - that Network is removed and no further dialog is presented.
