Menus don't work when accessing Thunderbird via message indicator

[Vladimir Mityukov]

Hi, I have Ubuntu 12.04 with kubuntu-desktop installed. The problem is reproducible under KDE session, so, I'm not sure if it's Thunderbird Indicator or plasma-widget-message-indicator's bug. It's quite strange, anyway ;-)

Here's how it works on my station:

1. I open Thunderbird via runner or menu (usually it's auto-started);

=> everything works Ok at this point.

2. At some time I access Thundebird via Message Indicator applet (no matter if I click master Thunderbird record or specific folder name with a number of not read messages);

=> I can click folders and messages with left mouse button and get appropriate reaction. But the following actions are broken:

a). If I click any item in the main menu (Files/Edit/etc.) -- nothing happens (it neither expands nor displays any other reaction);

b). if I click on a message with a right mouse button -- there is a popup menu shown for a very little fraction of second and then disappears immediately). So, I can't use context menu either.

Note: there are no error messages in the terminal, while I'm doing all this staff. The only message I get is when I quit the aplication:
$ thunderbird
Error: No such tab mode: chat
-- Exception object --

get_selected()@chrome://messenger/content/chat/imconv.xml:121
()@chrome://global/content/bindings/richlistbox.xml:576

^^^ but this same message I get even if I've not used message indicator.

I have the same problem as Vladimir on Kubuntu 12.04.1
