Reassign of default keyboard shortcuts used by katepart fails

[Gregor Mi]

Hi,

I am using kdevelop 4.6.0. I reassigned (for example) the F6 key - which
is set by the katepart - to Build action. This works well at first but...

when switching tabs or at the latest when I restart kdevelop the
katepart keyboard shortcut is restored which leads to ambigous keyboard
assignment message:

"The key sequence 'F6' is ambiguous. Use 'Configure Shortcuts'
from the 'Settings' menu to solve the ambiguity.
No action will be triggered."

Is this a known bug?
