Unsolved Ambiguous QShortcut creates an unwanted dialog

[Glax]

If I create a QShortcut with the same key sequence as a QAction, when I press the key sequence I get a dialog saying:

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

Is there a void to suppress that? I want to handle this thing on my side using QShortcut::activatedAmbiguously and not have the message appear.
