      extra/qt5-base 5.4.1-2 (qt qt5) [installed]
      (and the rest of the qt5 package set)

      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.
