Hi,

I have a library that, sometimes, when calibre starts, throws this exception: "TypeError: QAction(): arguments did not match any overloaded call"

Spoiler:

calibre, version 3.46.0
ERROR: Excepción no considerada: <b>TypeError</b>:QAction(): arguments did not match any overloaded call:
overload 1: argument 1 has unexpected type 'unicode'
overload 2: not enough arguments
overload 3: argument 1 has unexpected type 'unicode'

and calibre ends. The next time it starts there is no problem. It only happens in a specific library (I have more than 10 with the same plugins, although not the same virtual libraries or views).

I don't know what to look at.
