RegEx search breaks with some characters

Bug Description

Do a regular expression search for ")" (without quotes). When you click "Find", the button's caption changes to "Stop", the input box is disabled. Clicking "Stop" will change the caption back to "Find", but the input box remains disabled and doesn't become usable again until you close the current window.

The console displays the following error:
Traceback (most recent call last):
  File "/usr/lib/scribes/GenericPlugins/SearchSystem/", line 36, in __pattern_cb
  File "/usr/lib/scribes/GenericPlugins/SearchSystem/", line 27, in __regex_object
    regex_object = compile_(pattern, flags)
  File "/usr/lib/python2.6/", line 190, in compile
    return _compile(pattern, flags)
  File "/usr/lib/python2.6/", line 245, in _compile
    raise error, v # invalid expression
sre_constants.error: unbalanced parenthesis

The reason here is the obviously invalid RegEx with an unescaped parenthesis, which is up to the user to get right, but the editor should handle it gracefully and make the input field editable again to give the user the opportunity to correct their mistake.
