Problem description

I tried a few weekly builds for FC1.1. It frequently leads to error messages during startup related to cached icons, e.g.

Cannot find icon: /home/xyz/.cache/FreeCAD/Cache/AddonManager/MacroIcons/Macro_3D_Parametric_Curve.png
Cannot find icon: /home/xyz/.cache/FreeCAD/Cache/AddonManager/MacroIcons/Parametric_Curve_FP.svg
Cannot find icon: /home/xyz/.cache/FreeCAD/Cache/AddonManager/MacroIcons/FCTexture.png
Cannot find icon: /home/xyz/.cache/FreeCAD/Cache/AddonManager/MacroIcons/120px-FCBmpImportScreenshot.png
... quite a few more

Once I manually copied icons from other places around ~/.local/share/Freecad/Macro/ to this directory, but apparently the cache dir gets emptied from time to time and icons are not reinstalled even after updating the addons. It is however not fully empty, it contains BSpline3D_icon.xpm and Macro_CenterOfMass.svg.
Any idea why this happens or how to prevent it?

Why are the icons copied there, anyway? Isn't is more logical to keep them at the same space as the addon code?

Full version info

happened in several weekly builds over the last months

Are those macros that you have installed to a toolbar?

[g3grau]

Yes, I think you are right, they appear as white questionmark on a blue circle (10 in total). That is the "Auto-Created Macro Toolbar". There is one icon (Center of Mass) which appears white-on-white but that doesn't seem to cause an error message.
