Version:           2.5.999 (using KDE 4.6.0) 
OS:                Linux

If the program in a Konsole tab sets the xterm title to something containing an ampersand (&), and the tab's title is set to "%w" (or I assume any string containing %w) the tab parses it as if it were a hotkey definer (the hotkey works, the character directly after it is underlined).

Interestingly, Konsole's window title displays the ampersand.

Reproducible: Always

Steps to Reproduce:
1: Set a tab title to %w
2: Have a program set the xterm title to a string containing & (for instance "&example"
