z-axis problem: dialog freeze

[Sewi]

Use any Padre document editor tab (it won't freeze/crash Padre):

• Open the find or the replace dialog
• Type something which doesn't exist into the search text box
• Start searching
• Click the search button again without closing the "nothing found" popup

The dialog is frozen but in front, the popup is between the dialog window and the Padre main window.

There might be other dialogs which got the same problem, but I tried only those two so far.

OS: Ubuntu 9.04
