Description of problem:
When I work in Libreoffice Calc, it frequently happens that I open a dialog window (for example the dialog used to change the width of a column), make some edits, close the dialog, and then Libreoffice locks the keyboard. I am then unable to re-activate the keyboard, but I can use the mouse to shut down Libreoffice and restart.

Notes:
1) I have ibus configured in the im-chooser, with English and Japanese activated as input methods.

2) When the problem occurs, the keyboard is only locked in Libreoffice. I can use the mouse to switch to a non-Libreoffice window (e.g. a Konsole) and there the keyboard continues to work.


Version-Release number of selected component (if applicable):
libreoffice-calc 3.5.2.1-6.fc17.x86_64
ibus 1.4.99.20120428-1.fc17.x86_64
ibus-mozc 1.5.1053.102-1.fc17.x86_64

How reproducible:
It happens about every second time I use a dialog.

Steps to Reproduce:
1. Use the im-chooser to configure ibus. Enable English and the mozc method for Japanese
2. Restart X to ensure the ibus methods are fully loaded (there is  no need to actually type anything in Japanese)
3. Open a spreadsheet in Calc
4. Right-click a column header and select the option to modify the column width
5. Modify the width and click OK
6. If that does not trigger the bug, repeat 4 and 5 a few times
  
Actual results:
The keyboard is locked and only the mouse is left.

Expected results:
No keyboard locking.

Additional info:
Notes: I use the language packs for Japanese, and have the environment set to the Japanese locale. I don't think that is necessary to reproduce the bug, though.
