As noted, it's been quite some time since I read the QPL, and I won't
pretend to have an opinion on the DFSG-freeness of it.  You may instead
read my first comment as, "if the QPL permits redistribution, it should
*at minimum* be ok for non-free."

Googling suggests there has been some disagreement in the past as to
whether QPL is DFSG-compliant, though the last word standing on the
subject seems to be that it is.
