Substitution blocks the application

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Installed with setup.py install Autokey
2. Open autokey-gtk
3. New >> Phrase
4. Enter a new name: stupen
5. In the textbox I put: stupeň
6. Paste using Clipboard (Ctrl+V)
7. Abbreviation: stupen

What is the expected output? What do you see instead?
When writing "stupen", it should substitute it for "stupeň", however, the app 
gets blocked and white spaces are displayed instead of the substitution.

If a second time is written "stupen", then the keyboard gets blocked.

What version of the product are you using? On what operating system?
0.71.2
Ubuntu 12.04

Please provide any additional information below.

OK, I made a little patch to solve this issue.

I just ran this and found many more references to set_text() that should 
probably also have the "-1" argument added to them:
grep -rIF '.set_text(' /usr/lib/python2.7/dist-packages/autokey
