It may be related to the linkage of pthreads in libGL, but i don't think
that the bt is a sign for it. Every bt has the line #3 in it, independent
from gl. I think it is the way how apps are started from kdeinit and
KCrash captures the crash (i may be wrong though.)

i attached gdb to a running nspluginviewer by hand:

# gdb nspluginviewer 4674
.... skip lots of output ...

It may be just a bug in the pluginviewer related to the unloading of libs
(_fini in libflashplayer.so) and not a general problem with the linkage 
of gl in qt.
