Arch Linux
extra/qtcreator 3.3.2-1 [installed]

extra/qt5-base 5.4.1-2 (qt qt5) [installed]
(and the rest of the qt5 package set)
Description
This probably turns out to be a Qt bug though...
1) open any C++ source file
2) put the cursor on some interesting declaration or function argument
3) press F1
So I tried running it in gdb to get a backtrace (which is only so much help since it's not a debug build):

FWIW, the messages are referring to qch files that I just built, by running make docs on the 5.5 branch. Creator apparently detected them automatically and tried to use them.
I'm using the Arch packaged version of Qt Creator.
