Comment (by perveilerj at yahoo.com):

 I finally got some time to look into this again so I updated to r9258 (in
 the fixes branch, didn't want the new mythui stuff to add another cross
 product), rebuilt, and reran.  Same symptoms (hanging on the "no tuners
 available" dialog), but this time I didn't get a corrupted stack.  I also
 fixed the problem with my last backtrace (I didn't have the
 LD_LIBRARY_PATH set to the system debug libraries), so the new backtrace
 is a lot more informative.

 Thread 5 seems to be the dialog thread, and it seems to be going to sleep
 while waiting on a QT mutex of some sort.  I'm not too familiar with qt's
 innards, though, so perhaps this is normal?

 I tried running valgrind --tool=memcheck (I built with --enable-valgrind
 this time around) but things got a little flaky (most of the time I'd get
 a segfault before I got to my error point).  Since the stack corruption
 went away I didn't want to spend too much time with it, but if someone
 thinks it's helpful I can fight with it some more.

 Thanks,

 --Jack
