Crashing when copy and pasting frame

[schwarzgrau]

I wanted to copy and paste some keyframes on a layer. While it still works when copying the frame if I paste in on the same layer TVPaint freezes and I can't do anything anymore. If you would like to I could attach a project file.
By the way it only crashes if I use shortcuts. If I use the top menu for pasting it wont freeze.

Check your Keyboard shortcut list for multiple assignments of actions to the same keystroke?
