Hmm, I am using pretty much the same settings for all 3 machines (Suse 
0.20, Fedora 0.20, Suse svn head).
On all 3 machines, I am getting the mythtranscode segfault with the 1st 
sample, the queue slot message with the 2nd sample and both samples play 
fine.

When preparing the sample for ticket #2496, I started with a length of 5 
MB and was surprised, that it crashed. Then I increased the size to 10, 
20 and 30 MB and 30 MB was the first that did not crash and showed the 
"No more queue slots!" message from the ticket.

Here is gdb info from the segfault with svn head:

Program received signal SIGSEGV, Segmentation fault.
