Eeschema error when using drag (G) shortcut on a component

[Sebastian Haas]

The error (MsgBox)in eeschema says the following:

Warning
HandleBlockPLace(): m_mouseCaptureCallback
= NULL

with only on button to press (OK)

This happens everytime I am trying to drag a capacitor, or a resistor (I did not test other components) by clicking the component with my left mouse (trackpad), followed by the shortcut (G) and immediately after that I press left mouse again to place it somewhere. Then the message box appers with the text above. (Using the drag option from right-click menu works fine)

After closing the message box, sometimes I can no longer select any component. I still can safe the schematic but habve to close eeschema before it works again.

If the resistor is connected with another component by a wire. The wire disappears after pressing the the drag shortcut (G).

Appears to be a timing issue of some sort. I managed to reproduce it once, but it's quite difficult to trigger.

[Wayne Stambaugh (stambaughw)]

I think an acceptable fix would be to just add an assertion and return if no mouse capture callback is set. That's really what should have been done in the first place as it should not occur and is merely a warning for developers. User should never see this in release builds. I will make it so if there are no objections.
