Checkbox Toggling Does Not Correspond With Mouse Clicks Or Spacebar

[CrYpTiC_MauleR]

OS: Xubuntu 13.04 x64
Grsync: 1.2.3-1ubuntu1

Steps To Reproduce:

1. Create 4 additional regular sessions so 5 total (includes default)
2. Create a session set
3. Mark all checkboxes for the sessions created in step 1

Expected Result:

The checkboxes are checked by clicking the corresponding checkbox

Actual Result:

The first 3 checkboxes can not be checked at all, even if using spacebar. If the 4th checkbox is clicked the 1st checkbox gets marked. If the 5th checkbox is clicked the 2nd gets marked and so on. Using the spacebar has the same effect as using mouse.

Status changed to 'Confirmed' because the bug affects multiple users.

I have been able to check one checkbox, so I was able to get the checkboxes checked by manually editing the grsync.ini file in my /home/gilgamesh/.grsync folder, copying the one existing entry for the session set and pasting and modifying for the sessions I wanted to add.
