This breaks:
 ./ffmpeg -i  ~/tickets/1726/Mono.thd -bitexact -t 5 -y file1726.wav

video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown
Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)
Conversion failed!

vs.

size=     938kB time=00:00:05.00 bitrate=1536.1kbits/s speed= 102x    
video:0kB audio:938kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.004583%
 
sample probably here:
