Version: 1.11.3 (using KDE 4.2.3)
Installed from: Slackware Packages
If I double click on a message in the message list to open it in a new separate window, and I try to copy some selected text to the clipboard with CTRL+C, KMail says that:
"The key sequence 'Ctrl+C' is ambiguous. Use 'Configure Shortcuts'
from the 'Settings' menu to solve the ambiguity.
No action will be triggered."
In the Configure Shortcuts dialog there are two Copy actions, both assigned with the CTRL+C shortcut. There should be only one Copy action.
Confirmed in trunk
