Comment 6 for bug 577111

I need to do special research to discover a way to guaranteed reproduction of th bug. :-)
The results on the Ubuntu Lucid and Karmic are the same...

So, there are some steps to see the bug:
1. Call menu commands: Edit --> Preferences
2. Recall Modules Tab
3. Select any plugin
4. Click About_module button
5. See About window that has normal size
6. Press Close button in the this window (not at the window title-bar!)

7. Do steps 4, 5, 6 - all will be OK

8. Click About_module button
9. See About window that has normal size
10. Press close button AT THE TITLE-BAR
11.Click About_module button
12. See About window that has ZERO-SIZE (you can close it by system menu command)

13. Do steps 10, 11, 12 to repeat a problem

After restart GTG situation will be the same.

Those steps are the same on the Karmic and on the Lucid on 2 different computers.
Sorry for incomplete initial bug report.
