Cannot reopen popup windows, context menus, etc. after minimizing KTorrent

[Kevin T]

This bug was previously reported to KDE here: https://bugs.kde.org/show_bug.cgi?id=305816
We have concluded that the bug is likely in Unity.
The following is a copy-and-paste of the original report (please see the page above for more details and a short discussion about the bug):

Running Ubuntu 12.04 x86, but I've had this problem since 11.04. Always running latest KTorrent version (currently 4.1.3). It is not a major problem, but can be irritating.

On first startup, everything works fine. Right-clicking torrents causes context menus to show up, the configure KTorrent window works. However, after closing that window/context menu/etc. and then minimizing and subsequently restoring the window, anything that was opened before no longer opens properly. Anything that was not opened before is still fine.

When right-clicking for a context menu, the GUI seems to recognize that the user is trying to open a context menu and behaves as if one did open. It highlights the torrent, and then clicking empty white space one keeps the torrent highlighted (as if the user just closed the context menu), and then deselects the torrent after a second click.

The problem persists until KTorrent is fully closed (not just the window). A fresh start restores everything.

Note: This problem does not occur if the user closes the KTorrent window instead of minimizing. At the same time, the problem persists if the user only closes the window.

Reproducible: Always

Steps to Reproduce:
1. Start up KTorrent. Open the Configure KTorrent dialog box, or right-click a torrent to bring up a context menu.
2. Close the dialog box or context menu. I use the Cancel button for the settings dialog, but I don't think it should make a difference.
3. Minimize KTorrent to the task bar (don't close the window). Restore it. Try to open the Configure window or context menu again.
Actual Results:
If the Configure KTorrent window was opened before minimizing, it will not open anymore. If a torrent was right-clicked and the context menu shown, doing so will not open the context menu after minimizing and restoring.

Expected Results:
The Configure KTorrent window and any context menus should show up as per normal.

I started with Ubuntu 11.04 on this computer and have upgraded through 11.10 and now 12.04. The problem has been persistent throughout.

There is no special configuration that I'm using, and there are no proprietary drivers installed. It is just the default Ubuntu installation with the Unity desktop.

I have a lot of background programs running but I don't think they should be causing the problem.

CPU/Graphics: Intel i5 2400 with HD Graphics 3000.

Since the developers think it's a bug in Unity, assigning to the correct package.

Wow, I didn't realize it would take more than a year for this to get some attention.

Anyway, I can no longer reproduce this bug, so it might have been fixed either intentionally or unintentionally.
