Bug#36313: Key bindings dialog doesn't work

[timo at teifel.net]

Package: kdevelop
Version: 2.0 (using KDE 2.2.0 -11)
Severity: normal
Installed from:    Red Hat Linux 7.2
Compiler:          gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)
OS:                Linux (i686) release 2.4.7-10custom
OS/Compiler notes: 

Hi,

i tried changing the predefined keys, especially the key F5 to "Debug Run". It is already assigned to "next bookmark", so I changed this to Ctrl+Shift+T.
After that I tried to assign F5 to Debug Run, but KDevelop still said that F5 would be used by another Command.
I searched for the command which blocked the F5 Key, and found it: it's an empty command at the bottom of the list, assigned to F5. I'm pretty sure this wasn't there before.
The Radiobuttons to change the Hotkey for that command are disabled, so I can't change that Key anymore.
Is there a workaround known?
Thanks
Timo
