Qt creator crash on Arch Linux when I "search" a keyword on documentation

I'm on Arch Linux

I run qt creator, I go on "Help", "Contents". In the left panel I click on "Contents" in the top and I select "Search", I write a keyboard to search and I click on "Search", Qt creator crash.

runnning qtcreator on the terminal I can see the stderr:

Launching qtcreator I get:

{{qtcreator }}

{{  Error: No such file or directory}}

Then, when I search a keyword I get:
