Using quickfilters-3.4.2-sm+tb in Thunderbird 38.8.0, Windows 8.1 64bits

If I right click a message which is in a local folder : "QuickFilters : create filter from message..."
I get an error : "Tried to create a filter 7 times, but didn't work out [and more text]"

Drag and drop gives the same error message.

(note : in Account Setting - Server Settings - Advanced : inbox is set to Local Folders, for all my accounts)

Any known conflict with some extension ?
(I have about 30 of them, if needed I could provide the list)

Edit :
most issues are already solved by the developper in the pre-release of this AddOn.

Questa recensione riguarda una versione precedente (3.4.2) del componente aggiuntivo. 

Please can you go the official bug site here:

38 is rather old as well, I am currently testing with v60. The 2016 ESR version was 45, the current one is 52, see also:
